Proposal | Heatmap visualization

contribution can be reduced to this form:

(word, timestamp, x, y)

Given a square grid of areas inside landscapes for each word it's possible to count the number of contribution, then we can represent that distribution with a 2D heatmap.
A grid of heatmap or a composed heatmap (RGB with 3 word, transparency) could then be showed to user inside an analytics page
