The data shown here comes from Flight Delay Analysis Dataset

This chart is a combination of two view/charts - One is a map of the United States showing the "Major U.S. Airports based on Departure Delay" and another is a histogram showing the "Total Departure Delay for every hour of the day". We combine both these charts to show the "Major U.S. Airports based on Departure Delay grouped by time of day and it includes brushing".

The color saturation denotes the total Departure Delay for that airport. The names of the city & state are shown on the tooltip when you hover over the data points on the map. The state also gets highlighted when you hover over it. You could also Pan & Zoom the map to view the major airports of specific states.

Brushing with React Performance Optimization is included in the histogram linked to the map.

The intent of this graph is to map each flight to it's destination location(within the U.S.),grouped by time of the day with a semitransparent circle to show darker regions as the airports with higher flight departure delay density.

I used the U.S. Geo Map of State Boundaries for the underlying map.
