H3 getting started

Question

I'm new to geospatial indexing and found H3 to be really interesting. Currently messing around with the several different functions on API, but my question is how do I render the H3 cells to a map?

What map do you suggest, and how do I go about it?

Kind regards,

Mo

The answer depends partly on what version of H3 you're using - JS, Python, Java, etc. In general, the easiest way to render H3 cells is to use h3ToGeoBoundary to get each cell as a polygon, then encode this as GeoJSON or a similar standard format and load that in your map (which could be a web map like Leaflet or MapboxGL, or an application like QGIS, or some other rendering library).

You can see rendering approaches using MapboxGL in the H3 tutorials on Observable
In Javascript, you can use the geojson2h3 library to more easily convert between H3 and GeoJSON
