It visualizes the estimated visits from Census Tracts to each place of interest around Philadelphia. Each marker indicates a place of interest. Markers are grouped into clusters, which are color coded and numbered based on the total amount of estimated visits to its collective markers. Hover over a cluster to see a preview of its place markers and origin tracts. Census tracts are color coded, with the most opaque giving the most visitors and the least opaque giving the least visitors. Markers are color coded similarly to clusters. Click on a marker to view more detailed information about its specific place of interest. Median Dwell measures the average stay a visitor spends at that location in minutes. ` : `## Tracts Visualization This view shows our data from the perspective of Census Tracts. It visualizes the estimated visites to places of interest from each Census Tract around Philadelphia. Each Tract is color coded by the amount of outgoing people, with the most opaque giving the most people. Hover over or click on a tract to see all the destinations people from that tract are arriving to.
