Have branch with animated circles/heatmap/clipping experiment

[peterdesmet]

I think it's useful to be able to go back to these features. Either we tag them in some way or we create branch with all of those.

@bartaelterman, what do you think would be the best way.

[peterdesmet]

Decided to create tags:

• clip
• circles
• heatmap

[peterdesmet]

Bart, can you create a release for the heatmap experiment and maybe close the branch?

[peterdesmet]

@bartaelterman, in what branch is the heatmap code for the flow viz? Can we create a pre-release for it?

Also, any more relevant info in these branches that is not included in any of the releases?

• https://github.com/enram/bird-migration-flow-visualization/tree/timechart-overview

[bartaelterman]

The timechart-overview branch is quite interesting. It contains the the density as a scatterplot at the bottom of the viz. We wanted a line chart however, so that's why we never released it. But still a useful feature.

The heatmap code is in the context branch. If I checkout that branch and do a git log | less I can find a commit (f1ab469) that says show density heatmap. However, that code is broken. It turns out it cannot find the files in the ../data/ folder (even if you start your server in the viz folder, which is expected). You can fix that, by modifying the paths in settings.js. Make them all /data (so remove the two dots) and then launch your server in the root folder instead of in the viz folder. In my case, that works. I can now run a visualization with density displayed as a heatmap. The time chart is apparently also in here, but it's not interactive.

However, bear in mind that this code was done on an old version of the code. I'm not sure whether it will be easy to do on the new version.

Ok, will keep the two branches in case we have a chance to revisit this.
