Interactive maps are powerful tools in a visual journalist’s repertoire because they can simultaneously present data and geographic information. In the interactive map, How fast is the LAFD where you live? The Los Angeles Times analyzed more than a million runs by the fire department over a five-year span. The graphic compares the runtime of fire fighters in the Los Angeles area to the national standard. Rescuers are expected to arrive at all 911 calls within six minutes.

At a glance, the viewer can identify trends in the data relative to geographic locations. For example, just north of Hollywood, the LAFD consistently struggles to respond in less than ten minutes. This data is alarming, because in emergency situations, time is precious. While the map, is effective in its own right, adding interactivity adds another layer of engagement so that the viewer may dive deeper into the information.

A few features stand out. First when scrolling over a hexagon, viewers can see the number of responses, the nature of the call and the response time. In addition, viewers can place markers on the map the identify all of the LAFD fire stations.  The data overlays the map in a hexagonal grid. This interactivity provides an exemplary user experience, allowing viewers to easily analyze large datasets at a glance and dive deeper into the data, if they so choose.
