Objects in OpenStreetMap are often the cumulative product of multiple edits. This visualization displays a point for every edit of a specific type (building, highway, amenity, etc.). Using a heatmap style, the density of these points then shows the relative editing activity for any given time period.
The editing history of each object was reconstructed with the OSM-Wayback utility. This utility turns historical extracts of the full OSM planet history file into a GeoJSON sequence of objects with embedded editing histories.
