Time for part 4 of the tweet-a-watt (the project formally known as ‘wattcher’) design documentation! In this section, we play with the Google visualization widgets to save us lots of time. I will show you how to take data from the Google App Engine datastore, turn it into JSON and then make it visualization-happy for nice Flash graphs. The code is also fully available in a google code repository so hopefully people with better software skillz than I can submit patches and help out.
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
