Baby steps in data visualization

So, in my last post months ago, I resolved to learn better ways of visualizing data online than creating graphs in Excel and posting them as images. Resolution kept!

I had another go with the food price data, using one of the new tools I’ve been playing around with.


I still have a tonne to learn, and it seems like there is a lot of innovation in this area. No one tool is perfect but after reading a bit on the Guardian’s Data Blog I’ve been playing around with Tableau Public (for maps and interactive charts) and Google’s Fusion tables (for maps). Google Chart Wizard seems wonky to me; when I’ve entered data—even for a simple bar graph—it built the graph but not accurately. Probably I don’t know how to work it yet. As for the other tools, I’m learning as I go.

Anyway, here’s a second go at the food prices chart, with updated (to Dec. 2011) food price data from Statistics Canada. (Here’s the link to the newest data, which may have already been updated since I built the chart.)

Any more suggestions on data visualization tools?
