Question 1

How do I add custom tooltips to a mapmap.js map?

Accepted Answer

Use the .hoverInfo() method with an array of property names from your metadata, as shown in the basic example. Customization options are detailed in the API documentation on the wiki, allowing formatted labels based on metadata specifications.

Question 2

mapmap.js vs Leaflet for thematic maps?

Accepted Answer

mapmap.js is specialized for data-driven thematic mapping with built-in symbolization and data joining, while Leaflet is more general-purpose for interactive base maps. Choose mapmap.js for statistical visualizations and Leaflet for location-based applications with tiles.

Question 3

Can mapmap.js handle real-time data updates?

Accepted Answer

It's not optimized for real-time; mapmap.js focuses on static or batch-loaded data via files. For dynamic updates, you might need to reload the map or use custom D3 integrations, which can be complex and are not natively supported.

Question 4

What are the license implications for using mapmap.js in a commercial project?

Accepted Answer

The AGPL license requires open-sourcing your project's code if you use mapmap.js, which may not suit closed-source commercial apps. The README suggests contacting the author for alternative licensing options if this is a concern.

Question 5

How to integrate mapmap.js with a React application?

Accepted Answer

Since mapmap.js is vanilla JavaScript, integrate it by using refs to mount the SVG element and managing lifecycle methods to initialize and update the map. There's no official React wrapper, so it requires manual effort and careful state handling.

Question 6

Does mapmap.js support TopoJSON files?

Accepted Answer

Yes, but it requires including the TopoJSON library as an optional dependency, as mentioned in the README. Once loaded, use the .geometry() method with TopoJSON files similarly to GeoJSON for efficient geometry handling.
