Hilbert Map of English words

This treemap is an experiment of how the Hilbert treemap approach based on base 4 numbers behave with some samples data. Even if they are not so significant for the purpose of the visualization, English words has been choosen as sample data.

Surprisingly, the creation of all the regions and tiles that can be seen by zooming in and out within the visualization is computed on the fly, client side. Turf.js has been used for merging:

• the quads generated by the base4 number algorithm into the polygons of the lowest level of depth
• the polygons of a certain level of depth to polygons of the upper
