This repo creates a bundle for a nebula.js selection layer. Hold the r-key to select. This module also requires a custom fork of pydeck that has the onSelect event and handler. This way you can get all the items selected.
Build the repo with
yarn
yarn build
This creates the file dist/bundle.js that has this custom pydeck extension. You need to import as shown in pydeck_example/selection_example.py. This requires a webserver that can serve the bundle. You then serve the bundle with: python -m http.server
Navigate to http://localhost:8080/selection_layer.html in your browser, which should render the visualization.
