8 years ago Added plot of NYC taxi data by hour, in commit bbc26cb7ad, originally starting from an example by Albert DeFusco. Examples, using a colormap with red (midnight), yellow (4am), green (8am), cyan (noon), blue (4pm), purple (8pm):
Seems like there is lots of structure there.
According to google maps, this is a taxi inspection station:
I guess it has different queuing locations for the morning (green) and evening (blue)?
We need examples of plotting 2D datasets that vary over time. One example would be to map the time of day of the NYC taxi data into a hue value (since hour-of-the-day varies circularly, as hue does), and then let the saturation or luminance show the density of pickups or dropoffs.
This plot would map from time of day to hue, but many other possible ways to show temporal data could be used. E.g. if we have dynamic trajectory/telemetry data, we should be able to play that back as moving dots for a given day, making an animation.
Similarly, we could make a model of the US Census data, extrapolating it into the future, and then construct an animation to show the changes over time
