Images as x-axis labels

June 2, 2016 | Jonathan Carroll

Open-source software is awesome. If I found that a piece of closed-source software was missing a feature that I wanted, well, bad luck. I probably couldn’t even tell if was actually missing or if I just didn’t know about it....Continue Reading → [Read more...]

Bad Neighbours (no, not the movie)

April 29, 2016 | Jonathan Carroll

Another day, another compulsion to see if I can do any better than someone’s solution. This one also comes from the FiveThiryEight Puzzler challenge courtesy of Xi’an The original challenge this time was The misanthropes are coming. Suppose there is...Continue Reading →

April 27, 2016 | Jonathan Carroll

This neat approach showed up recently as an answer to a FiveThirtyEight puzzle and of course I couldn’t help but throw it at dplyr as soon as I could. Turns out that’s not a terrible idea. The question posed is...Continue Reading →

Is it crowded in here?

March 9, 2016 | Jonathan Carroll

This was a neat graphic that someone made. It shows the population at a given latitude or longitude as a bar chart, overlayed on a map of the world itself. It shows where people live; the bigger the bar, the...Continue Reading →

January 28, 2016 | Jonathan Carroll

Have you seen the little shark-fins on top of some traffic light control boxes? Have you seen the new 'x minutes to y road' signs? Did you know they're connected? DPTI installed a heap of bluetooth sensors around Adelaide and...Continue Reading →
