given the end-of-year data about which stations are feeding which, there're significant imbalances that require a manual rebalance by a given bikeshare program.

click and drag to pan, scroll to zoom.

trying to find the best way to visualize the imbalances for a single station before I extrapolate to every inter-station relationship.

still work in progress...

Trying to get points from a CSV plotted on a map.

TODO:

1. map flickers when you move it
2. click-drag to pan moves slower than the mouse location
3. I don't have any geo features to provide context (OSM streets?)

Part of a series of examples. See:

1. mousewheel-zoom + click-to-center via projection
2. click-to-center via projection
3. click-to-center via transform
4. click-to-zoom via transform

This is a fork of mike bostock's vector tiles example.

I've just re-centered it around Minneapolis to see how it looks.

Looking for an easy way to do map visualizations, geo data is too fickle to learn without leveraging tons of examples

Adapting d3.geo.tile to show OpenStreetMap vector tiles. See also the static example.

no clue who made this, but ARTIST FOUND thank you @indyjoenz / cmang!

i have transcribed it here:

With the power of bash piping and a tiny python script you can see what css rules could stand to be merged into simple classes.
