If you hover over a red dot you will get the stop’s number. Interestingly if you zoom in enough, you will see that Google already has all the stops loaded and if you click on a little bus icon under a red dot, you will get the route info for that stop.

Have fun.

I decided to see what I could do with this data. Below is my first attempt. It is a “density” map of all the bus stops in Auckland.

Click here for a hi-res version that allows you to pan and zoom.

The initial version of the map only took about 30 minutes to create but I have spent a few hours tinkering with it since then.

Quick guide
Here is quick guide to the process if you want to try something like this yourself:

1. I extracted stops.txt from the data set
2. I then gpsvisualizer.com to plot out the stops as data points on map. I got it to output a 4096 pixel wide .svg file
3. Next I used Inkscape to edit the .svg file, adding the text & zoomed area and exporting the result as a  .png file.
4. Lastly I used the Google Maps Image Cutter to generate the pannable and zoomable version. The Google Maps Image Cutter is a pretty neat tool. It takes any big image, chops it into different resolution tiles and then spits out some html which uses the Google Maps API to view your chopped up image.

Next steps
If I get some more time I will try create some more visualizations. I’m thinking  it would be interesting to merge the bus stop density data with some population data. Also an animation showing 24hrs of bus movement compressed into a couple of minutes would be pretty nice too.

For instance, on Digg I came across a nice visualization showing the edits to the “Evolution” article on Wikipedia.

I was curious to see what the source of the visualization was but there was no credit on the image. Looking in the comments for the post I didn’t find anything about the source but I did find this link which shows the public acceptance of evolution in various countries around the world. It is interesting to see where the USA sits on the chart.

Mmm, looking at the URL for the original visualization I could see that the image was hosted on Amazon’s S3 service and contained a reference to twittypic. A quick Google search turned up this site twittypic.com which monitors Twitter looking for images and video that are referenced by tweets, in the assumption that things that are referenced to by lots of people would be of interest to others. Nice idea.

Sure enough on Twittypic I found this post which referenced the original picture which was hosted at http://www.research.ibm.com/visual/images/discover_mag.jpg shortening the URL turned up the Visual Communication Lab at IBM. Clicking on their projects link turned up (amongst other interesting things) history flow which was the tool used to create the visualization.

Wow, so from a Digg post I :

• Gained insight into the Evolution vs Creation “debate”
• Found out how widely Evolution is accepted
• Found a new site (twittypic) that I’ll be adding to me RSS feeds
• Found some cool tools for visualizations from IBM (check out Many Eyes)
• and added some more stuff to the web by writing this post

Love it…
