Datashader in a Pythia Cookbook

[ahuang11]

I personally would go straight to using hvplot, which wraps datashader at a high level, Gridded Data — hvPlot 0.9.0 documentation

Also, regarding census.csv

Really dumb question- location of good census data file?

I am looking to recreate the census heatmap shown on the Datashader front page: import datashader as ds, pandas as pd, colorcet df = pd.read_csv('census.csv') cvs = ds.Canvas(plot_width=850, plot_height=500) agg = cvs.points(df, 'longitude', 'latitude') img = ds.tf.shade(agg, cmap=colorcet.fire, how='log') or the file used in the census example: df = dd.read_parquet('./data/census2010.parq') For the life of me, I cannot locate the source for either of these files- what am I doing wrong???
