This site is currently under construction. The direction I intend for this site to take is as a place to publish analytical insights derived from open data. I have a page called [Data Lab](/data-lab) where I publish interactive analytical dashboards, a blog to publish tutorials and thoughts on various related topics, and a [data downloads](/data-download) page for data access.
