Marker map
Updated a year ago to v4.3.1 by Flourish team
How to use this template
What's it for?
Showing locations on an interactive map. Useful both as a "locator" map to show a few places, or as a "data" map with many markers filterable by category. Places can be marked with emoji, icons from Font Awesome or uploaded images.
How to get started
- At a minimum, you just need a spreadsheet of places with columns for latitude and longitude. Point to these columns and your markers will appear on the map!
| category | latitude | longitude |
| Tube Station | -6.081689835 | 145.3919983 |
| Tube Station | -5.207079887 | 145.7890015 |
| Comment | -5.826789856 | 144.2960052 |
- Next you'll need to style your markers by choosing their image/emoji/icon, colour, etc. This can be done in three ways:
- If you want all the markers to look the same, just set the default styling in the Markers settings panel
- If you want to specify individual styles, add columns to your data sheet for marker, size, etc and make sure these are set in the column selection area
- Or if you want to style markers based categories in the data (see below)
How to specify markers
When entering an marker style in one of the tables or in the settings panel, you have three choices:
- Type or copy and paste an emoji
- Type in the name of a Font Awesome icon such as "house" or "dog" (you can find a full list of available icons here. You can include or miss out the "fa-" at the start fo the name.
- Upload an image, by clicking the image upload button or right-clicking on a spreadsheet cell. Uploaded images can be no larger than 1024Γ1024 pixels.
Working with categories
If your data has a category column you can style your markers at the category level. First make sure the category column is specified in the main data sheet. Then add a row in the "Categories" data sheet for each category you'd like to style. For example:
| Category name | Marker |
| Tube Station | π |
| Comment | fa-comment |
Customising the inset map
The inset map helps the viewer put the current map view in the context of a larger area: a country in the context of the world, say, or a city in the context of a country. By default, if enabled, the inset map shows a globe. But you can set the map to show any region you like by uploading one or more regions (in GeoJSON format) to the "Inset Map Regions" data sheet. Alternatively, if you just want one or more countries, you can copy the relevant row(s) from Regions datasheet of our Projection Map template.

FAQ
I don't have lat or lng locations, only place names You'll need to geocode your data. Various online tools that can help with this. Paying customers can contact the Flourish team for more help and advice.
How do I reset the initial zoom and centre of the map? The map automatically sets its initial zoom and centre to contain all your icons. If you want to override this you have two options. First: restrict the bounds of the map (under Base Map > Viewport). Second, create a story: hit the "Create a story" button and drag the map into whatever zoom/pan state you like, and it will be automatically saved. If you don't want the navigation bar at the top, choose "None" from the "Navigation" menu.
How do I change the colour of the icons? Font Awesome icons can be given custom colours using the Colour data bindings or settings. Note that this won't work for emoji or images.
How can I tell a story with my map? If you'd like to give the audience a tour of the data and highlight different locations or regions one by one, create a Flourish story from your visualisation, then add multiple slides to highlight different places, as in the example below.

API information
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/3d-marker-map
version: 4
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: {
markers: [
[ "MarkersColumn1Value1", "MarkersColumn2Value1",
[ "MarkersColumn1Value2", "MarkersColumn2Value2",
[ "MarkersColumn1Value3", "MarkersColumn2Value3",
...
],
icons: [
[ "IconsColumn1Value1", "IconsColumn2Value1",
[ "IconsColumn1Value2", "IconsColumn2Value2",
[ "IconsColumn1Value3", "IconsColumn2Value3",
...
],
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-marker-map",
version: "4",
bindings: {
markers: {
lat: 0, // index of a column in your data
long: 1, // index of a column in your data
},
icons: {
},
regions: {
}
},
data: {
markers: [
[ "MarkersColumn1Value1", "MarkersColumn2Value1",
[ "MarkersColumn1Value2", "MarkersColumn2Value2",
[ "MarkersColumn1Value3", "MarkersColumn2Value3",
...
],
icons: [
[ "IconsColumn1Value1", "IconsColumn2Value1",
[ "IconsColumn1Value2", "IconsColumn2Value2",
[ "IconsColumn1Value3", "IconsColumn2Value3",
...
],
regions: [
[ "RegionsColumn1Value1", "RegionsColumn2Value1",
[ "RegionsColumn1Value2", "RegionsColumn2Value2",
[ "RegionsColumn1Value3", "RegionsColumn2Value3",
...
]
}
}
All possible bindings that you can supply are shown in this example:
{
template: "@flourish/3d-marker-map",
version: "4",
bindings: {
markers: {
lat: 0, // index of a column in your data
long: 1, // index of a column in your data
image: 2, // index of a column in your data
name: 3, // index of a column in your data
description: 4, // index of a column in your data
photo: 5, // index of a column in your data
link: 6, // index of a column in your data
category: 7, // index of a column in your data
color: 8, // index of a column in your data
size: 9, // index of a column in your data
metadata: [10, 11, ...], // index(es) of column(s) in your data
},
icons: {
category_name: 0, // index of a column in your data
icon: 1, // index of a column in your data
size: 2, // index of a column in your data
color: 3, // index of a column in your data
opacity: 4, // index of a column in your data
},
regions: {
geojson: 0, // index of a column in your data
}
},
data: {
markers: [
[ "MarkersColumn1Value1", "MarkersColumn2Value1",
[ "MarkersColumn1Value2", "MarkersColumn2Value2",
[ "MarkersColumn1Value3", "MarkersColumn2Value3",
...
],
icons: [
[ "IconsColumn1Value1", "IconsColumn2Value1",
[ "IconsColumn1Value2", "IconsColumn2Value2",
[ "IconsColumn1Value3", "IconsColumn2Value3",
...
],
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:
{
markers: [
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
...
],
icons: [
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
...
],
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-marker-map",
version: "4",
bindings: {
markers: {
lat: "MarkersHeader1",
long: "MarkersHeader2",
},
icons: {
},
regions: {
}
},
data: {
markers: [
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
...
],
icons: [
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
...
],
regions: [
{ "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
{ "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
{ "RegionsHeader1": ..., "RegionsHeader2": ..., ... },
...
]
}
}
All possible bindings that you can supply are shown in this example:
{
template: "@flourish/3d-marker-map",
version: "4",
bindings: {
markers: {
lat: "MarkersHeader1",
long: "MarkersHeader2",
image: "MarkersHeader3",
name: "MarkersHeader4",
description: "MarkersHeader5",
photo: "MarkersHeader6",
link: "MarkersHeader7",
category: "MarkersHeader8",
color: "MarkersHeader9",
size: "MarkersHeader10",
metadata: ["MarkersHeader11", "MarkersHeader12", ...],
},
icons: {
category_name: "IconsHeader1",
icon: "IconsHeader2",
size: "IconsHeader3",
color: "IconsHeader4",
opacity: "IconsHeader5",
},
regions: {
geojson: "RegionsHeader1",
}
},
data: {
markers: [
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
{ "MarkersHeader1": ..., "MarkersHeader2": ..., ... },
...
],
icons: [
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
{ "IconsHeader1": ..., "IconsHeader2": ..., ... },
...
],
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-marker-map",
version: "4",
data: {
markers: [
{
lat: ...,
long: ...,
metadata: [...]
},
...
]
},
...
}
And the full list of all possible properties is as follows:
{
template: "@flourish/3d-marker-map",
version: "4",
data: {
markers: [
{
lat: ...,
long: ...,
image: ...,
name: ...,
description: ...,
photo: ...,
link: ...,
category: ...,
color: ...,
size: ...,
metadata: [...]
},
...
],
icons: [
{
category_name: ...,
icon: ...,
size: ...,
color: ...,
opacity: ...
},
...
],
regions: [
{
geojson: ...
},
...
]
},
...
}
