datashader_cli

Quick visualization of large datasets using CLI based on datashader. More information: https://github.com/wybert/datashader-cli.

• Create a shaded scatter plot of points and save it to a PNG file and set the background color:

datashader_cli points path/to/input.parquet --x pickup_x --y pickup_y path/to/output.png --background black|white|#rrggbb

• Visualize the geospatial data (supports Geoparquet, shapefile, geojson, geopackage, etc.):

datashader_cli points path/to/input_data.geo.parquet path/to/output_data.png --geo true

• Use matplotlib to render the image:

datashader_cli points path/to/input_data.geo.parquet path/to/output_data.png --geo true --matplotlib true
