 # This app has a Pydeck map that displays a scatterplot layer by default, and it allows the user to switch between HexagonLayer, HeatmapLayer, and ScatterplotLayer using a dropdown menu. The user can also adjust the properties of the selected layer using sliders and color pickers. Finally, the app displays a Three.js canvas that rotates a green cube.
