This is a rework of the visualization I did for the Dnevnik newspaper. The Ljubljana government was generous enough to give us a location database with information on species and location of every tree within city limits. I thought it would be nice to render every species on its own map, so that the distributions can be compared.
Instead of just drawing points where each tree is, I calculated distance from each building to all the trees, and increased the building “score” if a tree was within 150 meters distance. Then I colored the buildings according to the score – the darker green it is, the more trees in its vicinity.

The aforementioned article depicted the areas with higher potential for causing allergenic reactions due to specific tree species that grow there, but it also has a detailed map with every building colored in proportion with its distance from trees in vicinity.
