The most recent MRes Processing assignment was to show the flow of journeys from a day of London bike hire usage. My previous Processing visualisations have all been quite dynamic, the kind that run through data on their own. For this one I decided to take a different approach. It’s an interactive visualisation where the user can click on any of the bike hire stand locations to see where the journeys went to from that stand.
The when the app starts it looks like this
The size of the stand locations shows the number of journeys from that location. Clicking on a stand then shows which other stands those journeys went to
The brightness of the line indicates the number of flows from the clicked stand to the stand the line goes to.
Some of the stands didn’t have any journeys made from them – I assume that the stand existed but wasn’t fully open on the day the data is taken from.
If the user prefers to have more of an idea where the stand locations are, pressing space will display a map background instead of the more basic one
Overall I’m really pleased with how it has turned out. I think it’s quite useful for seeing the journeys made from each of the hire stands, and I like the way it looks.
