Pittsburgh Data Visualization: D3 and only D3

Patrick gave a presentation for the Pittsburgh Data Visualization Meetup on only D3, because there was interest after the previous meetup for more on D3.

Summary

Patrick started with a review of last time, on selections, data, callbacks, and transitions.

Then he went into the use of heat maps.

Finally, he went into forces.

I have to confess that I got lost in the presentation because of the volume of code presented and my unfamiliarity with the API. I believe that I’ve reached the limit of what I can passively absorb about using D3, and simply need to get down and dirty and create my own project.

I was also feeling really tired and on the verge of getting sick. I felt very cold in the room and did not have a jacket on me in the summer.
