Generate Hex Maps from your existing Spatial Data in less than 3 steps
Spatial Visualisation — Using the combined power of Turf and Hextile JavaScript libraries to generate hex maps
Having come across many articles, I do notice many individuals seek to generate hex maps for their current spatial datasets either for the sake of aesthetics (E.g. Dashboard visualisations) or to minimise spatial distortion from overlapping geometry features. Well, I have got good news for these individuals as I have recently discovered that the combined use of 2 JavaScript libraries — enables users to render the required output instantly, eliminating the hassle of adding any extra calculated fields in Tableau. This new functionality has been deployed onto my web app at https://tableau-data-utility.onrender.com/ for the convenience of users and for future usage. So, here’s a quick preview of the data transformation and resulting visualisations:
The above image does not involve any calculations in Tableau. The approach to this is simply pre-processing your GeoJSON formatted file into another GeoJSON file which renders hexagons instead of polygons.
Simply navigate to https://tableau-data-utility.onrender.com/ and input your spatial data into the web app:
