Projection map – an overview

What is it for?

Use this template to make data maps with region-shading and/or points as well as popups and panels to display information and geographic content. Adapt an existing example or upload your own geographic boundary file.

How to get started


    You can either select a blueprint in the template chooser or upload your own regions in GeoJSON format.

    TIP: Struggling to find the right regions for your map? Check out our GeoJSON repository where we’ve sourced, checked, and resized various region files ready for you to download and use in Flourish.


    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. Select “Merge with current sheet” upon importing your separate datasheet and select which column you would like to match and join your datasheets by. Learn more about merging data in this help doc.

    The Regions column bindings include Name and Label, Value, as well as an optional setting for Grouped regions. In addition, you can bind any additional column under Metadata for popups, which is a great way to add more information to your visualization without overcrowding your chart.


    Alongside regions, you can also draw points. For Points data, the template requires one row per point with at least a column for longitude 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. To add points to your map, switch to the Points tab within the Data tab.

    Under the Lines tab, you can add your own custom lines in a GeoJSON format. You may want to do this to indicate disputed borders, or to overlay your regions with features such as rivers. Read more about this here.

    You can choose from over 40 different map projections in the “Projections” settings in the Preview tab

    To add metadata to your popups and/or panels, supply the columns with your metadata to the “Select columns to visualise” panel in the Data tab. You can also include custom content and HTML to create layouts, formatting and images. You can learn more about this here.
