This is a "mapmaker" visualization of discretionary permit data from Development Services in San Diego. The data are 4,774 geolocated discretionary permits — those permits that require special approval — across 10 years. The visualization uses p5.js to build a map chronologically one permit at a time. The points representing the earliest permits are very red and get closer to blue over time so that the resulting map codes for time (red > orange > yellow > green > blue). The result is an "experienced" portrait of permit issue in San Diego over the last decade.
