The drought warning in New York City is a significant alert, drawing attention to the abnormally dry conditions that have persisted through the fall season.
Denise Lu utilized a heatmap to illustrate the duration of consecutive rain-free days, providing a visual representation of the precipitation measurements taken in Central Park.
The graphic serves as an event-driven visualization, focusing on the specific occurrences of dryness rather than revealing broader rainfall patterns across the region.
A potential idea is to reverse the color scale in the heatmap, which might enhance the perception of drier conditions by highlighting longer streaks with blank spaces.
