+
+> 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`
