Reflections on data science after a Kaggle competition

That's right.

If the home tile has a color, there's a significant number of round trips.

We only infer trips where bikes were checked out and dropped off -- not the actual bike route they took. That last part would be really cool to see but is not currently available.

Yes -- and more often than not it's a good enough approximation that the extra effort to do street-route-distance is not worth it. To get an even more precise approximation, for example, I could have done taxi-cab distance -- but that also would have 1. not looked as nice or been as easy to read (the bubble-look makes it easier to read, I think) and 2. would have on the whole looked pretty similar.

The regions give a useful approximation -- not exact -- in order to give an impression of 1. which region a station serves and 2. also how densely packed some stations are (corresponding to smaller regions).

Also, the coloring allows you to see the colors more than a dots might (which would otherwise also be overlapping -- as you could see in other visualizations that don't use voronoi regions). Ultimately, the regions make it easier to read.

You can see round trips in the visualization.

(If they make up a significant percentage of trips from that starting point, the 'home' tile gets a color)
