Anyone work with D3.js?

[mkchandler]

I'm wanting to make D3.js a topic for CodeAcross next month. Is anyone here knowledgable about D3.js, or know someone who is that would like to do a short presentation and intro to D3?

D3 is something that will be very useful for visualizing some of the open data that we have access to. Something I would like to tackle during CodeAcross is creating a visualization of city spending.

@jvrousseau or @DevinClark and probably an open call to the okcjs twitter account will get ahold of who you want.

I've done a bit with D3 at a couple of different levels.

NVD3 makes it super easy to drop in some pre-built charts and I've used it on a number of projects. http://nvd3.org/

I've also done a little bit with raw D3, which has kind of... unusual requirements for structuring your code.

I remember your presentation on NVD3, that looks like good stuff. I'd like to see if we could use a treemap to visualize the spending or budget. I've seen it done for some other cities, though I'm having trouble finding links at this moment.

Here's one for Philly: http://budget.brettmandel.com/

Oh, nice. Do we have that kind of tree like info?

[mkchandler]

I'm not sure haha. But we can get it if don't already have it.

Another good d3 piece for visualizing a budget is force layout, a la: http://www.nytimes.com/interactive/2012/02/13/us/politics/2013-budget-proposal-graphic.html. A great presentation on it: http://vallandingham.me/abusing_the_force.html

@jvrousseau Yeah, that's pretty awesome. Love the transitions between the different "views".

To give an update on this topic, we found someone to give a presentation on D3.js. I also received the FY2015 budget data from the city via an Open Records request. I will start a new repo and get it uploaded.

Repo has been created: https://github.com/codeforokc/okc-budget-data

Further discussion can take place over there.
