This app was created for a Energy.gov hackathon. Not sure what every happened with the hackathon, I don’t think they ever sent out the results. Anyways I used a simple native Android chart library for the charts and used Google charts for the interactive map of the US. Since that is a solution meant for Web apps and not for Native Android, I had to wrap it all in a WebKit component. Think it worked out well so I’ve kept it on the App store for now.
