Publish import scripts/pipeline for all US Census data

[alexkreidler]

The existing import scripts for the US Census don't include the ACS data that is in the graph.

I'm guessing all the data is originally from the ACS Summary File. It may be that you are generating the graph data from existing Google Public Datasets on BigQuery, or transforming the raw files.

Either way, it would be great to publish the scripts you use to convert that data into graph format.
