Projection map (beta)

Make data maps with region-shading and/or points. Adapt an existing example or upload your own geographic boundary file.

How to use this template

Projection map

Make thematic maps using a range of projections with your own geometric data.

Data requirements: Regions

Create shadeable geographic regions by uploading your own map data in GeoJSON format. The file should contain a FeatureCollection with each feature being a Polygon or MultiPolygon in unprojected (WGS84) coordinates. Each feature will become a row in the datasheet with the geometry in the first column and metadata (properties) in subsequent columns.

The metadata can be used for shading regions to make a choropleth map. Additional data from a separate source (an xlsx or CSV file) can be added using the merge option when importing data as shown below and in the video at the bottom of the page.

Data requirements: Points

Alongside regions, one can also draw points. For Points data the template requires one row per point with at least a column for longitudae and a column for latitude (both in decimal degrees). In addition, it is possible to shade points by (categorical) value and/or size points by (numeric) value.

Tips

  • Remove a region from a visualisation by deleting the corresponding row in the Regions datasheet.
  • Choose from over 40 different map projections in the Projections panel. In advanced mode the map can be centred around any point on Earth.
  • Use the Meta data for popups column selection boxes to add additional data to popups.

Credits

The default points data comes from the GeoNames dataset of cities with populations of above 150,000, http://www.geonames.org/export/.

This section documents API usage specific to this template, so for an introduction we suggest you refer to the generic API documentation instead.

template: @flourish/projection-map

version: 2

Template data

There are two different formats in which you can supply data to this template. Which one will be more convenient for you likely depends on the source of your data, as described below.

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:

    {
        choropleth: [
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            ...
        ],
        points: [
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            ...
        ]
    }

... but with the keys being the column headers from your source data instead. To tell the API how these 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/projection-map",
    version: "2",
    bindings: {
        choropleth: {
            
        },
        points: {
            
        }
    },
    data: {
        choropleth: [
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            ...
        ],
        points: [
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            ...
        ]
    }
}

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

{
    template: "@flourish/projection-map",
    version: "2",
    bindings: {
        choropleth: {
            geometry: "ChoroplethHeader1",
            name: "ChoroplethHeader2",
            value: ["ChoroplethHeader3", "ChoroplethHeader4", ...],
            metadata: ["ChoroplethHeader5", "ChoroplethHeader6", ...]
        },
        points: {
            name: "PointsHeader1",
            lon: "PointsHeader2",
            lat: "PointsHeader3",
            color: "PointsHeader4",
            value: "PointsHeader5",
            metadata: ["PointsHeader6", "PointsHeader7", ...]
        }
    },
    data: {
        choropleth: [
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            { "ChoroplethHeader1": ..., "ChoroplethHeader2": ..., ... },
            ...
        ],
        points: [
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            { "PointsHeader1": ..., "PointsHeader2": ..., ... },
            ...
        ]
    }
}

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

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/projection-map",
version: "2",
data: {
    choropleth: [
        {
            value: [...],
            metadata: [...]
        },
        ...
    ],
    points: [
        {
            metadata: [...]
        },
        ...
    ]
},
...
}

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

{
template: "@flourish/projection-map",
version: "2",
data: {
    choropleth: [
        {
            geometry: ...,
            name: ...,
            value: [...],
            metadata: [...]
        },
        ...
    ],
    points: [
        {
            name: ...,
            lon: ...,
            lat: ...,
            color: ...,
            value: ...,
            metadata: [...]
        },
        ...
    ]
},
...
}

State documentation

hovered_feature hidden

Selected feature. Region or point which is highlighted and which the popup should point to. If nothing is highlighted then this should be null. Otherwise it should be a string of the form <type>-<index>, where <type> is either "regions" or "points" and index is the corresponding (0-based) row index. For example "regions-0" or "points-134". When this value is not null, the sticky_hover property should usually be true.

sticky_hover hidden

Is the popup and highlighting fixed to the hovered_feature (true) or should moving the mouse over other features change which feature is highlighted?.

filter hidden

Points filter. An object whose keys are names of the colour categories (for points) that should be filtered out and whose values are (usually) something truthy.

zoom_transform hidden

Zoom transformation. An object specifying the transformation to zoom the map in on a region. It has five properties. k is the zoom level (k = 1 for no zoom, k > 1 for zoomed in). x and y are the negatives of the horizontal and vertical coordinates (0, 0 is the top left corner) the zoom is centred on. width and height specify the width and height (in pixels) of the map on which the transform is performed.
