How to use this template

What's it for?

Use this template to visualise flows between locations, or journeys.

How to get started

  1. You'll need two CSV or Excel files. One will contain the locations of the points shown on your map - the start and end points of your arcs. The other will contain the details of the arcs themselves.

  2. The locations file will need (at a minimum) columns for the location identifier, latitude and longitude. Here's an example:

    airport_id latitude longitude
    1 -6.081689835 145.3919983
    2 -5.207079887 145.7890015
    3 -5.826789856 144.2960052
  3. The arcs file will need (at a minimum) columns for the source ID and target ID of the arc. You can also include columns that can be used to specify the colour or thickness of the arc. Here's an example:

    source_id target_id airline
    1 2 American Airlines
    2 3 American Airlines
    1 3 United Airlines

FAQ

How do I reset the initial zoom and centre of the map? For the moment, you need to do this: (1) Create a story from your visualisation (2) Zoom and pan the slide to adjust the zoom and centre of the map (3) In the left-hand menu, under "Navigation", choose "None" (4) Publish the story.

How do I change the colour of the arcs? Two methods. If you'd like them all to be the same colour, use the settings in the settings panel. If you'd like the colours to vary with some property of the data, select a "Category" column in the data panel. Then return to the settings panel and choose the Categorical colour option.

How do I change the thickness of the arcs? Two methods. If you'd like to make all the arcs thicker or thinner, just use the "Thickness" setting to do so. If you'd like the thickness to vary with some property of the data, select a "Value" column in the data panel. Then return to the settings panel and choose the Categorical colour option.

How can I highlight different points on the map? Create a story from your visualisation, then add multiple slides to highlight different views of the data. See the example story below.

Template data

There are three different formats in which you can supply data to this template. The most convenient for you to use likely depends on the source of your data, as described below.

1. Array of arrays, and a bindings object

You can supply arrays of arrays to opts.data, which might look like:

{
    data: {
        routes: [
            [ "RoutesColumn1Value1", "RoutesColumn2Value1",
            [ "RoutesColumn1Value2", "RoutesColumn2Value2",
            [ "RoutesColumn1Value3", "RoutesColumn2Value3",
            ...
        ],
        locations: [
            [ "LocationsColumn1Value1", "LocationsColumn2Value1",
            [ "LocationsColumn1Value2", "LocationsColumn2Value2",
            [ "LocationsColumn1Value3", "LocationsColumn2Value3",
            ...
        ],
        regions: [
            [ "RegionsColumn1Value1", "RegionsColumn2Value1",
            [ "RegionsColumn1Value2", "RegionsColumn2Value2",
            [ "RegionsColumn1Value3", "RegionsColumn2Value3",
            ...
        ]
    }
}

where each array of arrays represents the rows in a data sheet.

To tell the API how the values from each column should be associated with the keys that the template is expecting, you must also supply an object attached to opts.bindings. (The meanings of the keys in the bindings object are documented below.) The minimal bindings you can supply for this template are as shown in this example:

{
    template: "@flourish/3d-arc-map",
    version: "7",
    bindings: {
        routes: {
            source: 0, // index of a column in your data
            target: 1, // index of a column in your data
        },
        locations: {
            id: 0, // index of a column in your data
            latitude: 1, // index of a column in your data
            longitude: 2, // index of a column in your data
        },
        regions: {
            
        }
    },
    data: {
        routes: [
            [ "RoutesColumn1Value1", "RoutesColumn2Value1",
            [ "RoutesColumn1Value2", "RoutesColumn2Value2",
            [ "RoutesColumn1Value3", "RoutesColumn2Value3",
            ...
        ],
        locations: [
            [ "LocationsColumn1Value1", "LocationsColumn2Value1",
            [ "LocationsColumn1Value2", "LocationsColumn2Value2",
            [ "LocationsColumn1Value3", "LocationsColumn2Value3",
            ...
        ],
        regions: [
            [ "RegionsColumn1Value1", "RegionsColumn2Value1",
            [ "RegionsColumn1Value2", "RegionsColumn2Value2",
            [ "RegionsColumn1Value3", "RegionsColumn2Value3",
            ...
        ]
    }
}

All possible bindings that you can supply are shown in this example:

{
    template: "@flourish/3d-arc-map",
    version: "7",
    bindings: {
        routes: {
            source: 0, // index of a column in your data
            target: 1, // index of a column in your data
            width: 2, // index of a column in your data
            filter: 3, // index of a column in your data
            category: 4, // index of a column in your data
            metadata: [5, 6, ...], // index(es) of column(s) in your data
        },
        locations: {
            id: 0, // index of a column in your data
            latitude: 1, // index of a column in your data
            longitude: 2, // index of a column in your data
            name: 3, // index of a column in your data
            category: 4, // index of a column in your data
        },
        regions: {
            geojson: 0, // index of a column in your data
        }
    },
    data: {
        routes: [
            [ "RoutesColumn1Value1", "RoutesColumn2Value1",
            [ "RoutesColumn1Value2", "RoutesColumn2Value2",
            [ "RoutesColumn1Value3", "RoutesColumn2Value3",
            ...
        ],
        locations: [
            [ "LocationsColumn1Value1", "LocationsColumn2Value1",
            [ "LocationsColumn1Value2", "LocationsColumn2Value2",
            [ "LocationsColumn1Value3", "LocationsColumn2Value3",
            ...
        ],
        regions: [
            [ "RegionsColumn1Value1", "RegionsColumn2Value1",
            [ "RegionsColumn1Value2", "RegionsColumn2Value2",
            [ "RegionsColumn1Value3", "RegionsColumn2Value3",
            ...
        ]
    }
}

2. Array of objects with arbitrary keys, and a bindings object

This format is most likely useful when you have data from an external source, such as CSV data loaded from d3-dsv. You should supply this attached to the opts.data, which might look like:

{
        routes: [
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            ...
        ],
        locations: [
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            ...
        ],
        regions: [
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            ...
        ]
    }

... but with the keys being the column headers from your source data instead. You must also supply an object attached to opts.bindings. The minimal bindings you can supply for this template are as shown in this example:

{
    template: "@flourish/3d-arc-map",
    version: "7",
    bindings: {
        routes: {
            source: "RoutesHeader1",
            target: "RoutesHeader2",
        },
        locations: {
            id: "LocationsHeader1",
            latitude: "LocationsHeader2",
            longitude: "LocationsHeader3",
        },
        regions: {
            
        }
    },
    data: {
        routes: [
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            ...
        ],
        locations: [
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            ...
        ],
        regions: [
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            ...
        ]
    }
}

All possible bindings that you can supply are shown in this example:

{
    template: "@flourish/3d-arc-map",
    version: "7",
    bindings: {
        routes: {
            source: "RoutesHeader1",
            target: "RoutesHeader2",
            width: "RoutesHeader3",
            filter: "RoutesHeader4",
            category: "RoutesHeader5",
            metadata: ["RoutesHeader6", "RoutesHeader7", ...],
        },
        locations: {
            id: "LocationsHeader1",
            latitude: "LocationsHeader2",
            longitude: "LocationsHeader3",
            name: "LocationsHeader4",
            category: "LocationsHeader5",
        },
        regions: {
            geojson: "RegionsHeader1",
        }
    },
    data: {
        routes: [
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            { "RoutesHeader1": ..., "RoutesHeader2": ..., ... },
            ...
        ],
        locations: [
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            { "LocationsHeader1": ..., "LocationsHeader2": ..., ... },
            ...
        ],
        regions: [
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            { "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
            ...
        ]
    }
}

(As before, the keys containing "Header" would be replaced by column names from your data source.)

3. Array of objects with template-defined keys

There is an alternative format you can use, which is likely to be easier to use if your data is not from a spreadsheet source. With this alternative format you supply your data to the template as an array of objects, attached to opts.data, where the keys must be those used by the template, as documented below. In this case there is no need to supply a bindings object, since the key names are already those expected by the template. The required properties in the data object are as follows (scroll down for a description of what each property is):

{
    template: "@flourish/3d-arc-map",
    version: "7",
    data: {
    routes: [
        {
            source: ...,
            target: ...,
            metadata: [...]
        },
        ...
    ],
    locations: [
        {
            id: ...,
            latitude: ...,
            longitude: ...
        },
        ...
    ]
},
    ...
}

And the full list of all possible properties is as follows:

{
    template: "@flourish/3d-arc-map",
    version: "7",
    data: {
    routes: [
        {
            source: ...,
            target: ...,
            width: ...,
            filter: ...,
            category: ...,
            metadata: [...]
        },
        ...
    ],
    locations: [
        {
            id: ...,
            latitude: ...,
            longitude: ...,
            name: ...,
            category: ...
        },
        ...
    ],
    regions: [
        {
            geojson: ...
        },
        ...
    ]
},
    ...
}

Meanings of the template data keys:

  • routes.source: The column containing the code for the arc's source. This should match the codes used in the Locations sheet
  • routes.target: The column containing the code for the arc's target, This should match the codes used in the Locations sheet
  • routes.width: Optionally, a column containing a value for the arc, which can be used to specify its thickness.
  • routes.filter: Optionally, a column to filter visible arcs by.
  • routes.category: Optionally, a column containing a category for the arc, which can be used to specify its colour. Over-rides the category in the Locations sheet, if both are specified.
  • routes.metadata: One or more columns of information to include in popups.
  • locations.id: The column containing the location code. Should match the codes used in the Arcs sheet.
  • locations.latitude: Latitude for each location, specified in decimal degrees.
  • locations.longitude: Longitude for each location, specified in decimal degrees.
  • locations.name: Optionally, a column containing the name of the location, to show in popup
  • locations.category: Optionally, a column containing the category of the arc, which can be used to specify its colour.
  • regions.geojson: geojson
