Vega visualization

IDEAS:

• Scan the CSV to guess column data types - numeric vs. text
• if it is easy, we could also identify certain types, phone numbers, lat/lon or zipcode, email address etc.
• Allow users to pick: X Axis, Y Axis, Plots. We do our best to create a graph with the XY fields as the axis, ordered, and a scatter plot of the numeric values. Maybe choose between a scatterplot, barchart, pie chart, other basic ones? Could pick a column for color or category?
• Show basic stats of the fields: for numeric, mean/min/max etc. for text, distinct values count, maybe a list if there aren't too many. Show a map of locations if we find them and there aren't too many. Earliest/latest times we find.

Some vega examples for inspiration (https://vega.github.io/vega/examples/):

Pick columns to build a tree hierarchy:

Word clouds:

Multiline

Fancy stack:

Some of these would be difficult to make generic, but look pretty cool!
