<!-- Greeting --> Hey @AakashGandhi1! I'm here to help you with any bugs, questions, or becoming a contributor while you wait for a human maintainer. Let's tackle this together! <!-- Answer --> I found a similar closed issue titled "Point Color not reported in deck.gl multilayer" on GitHub, but no solution was found in the comments <sup>[[1]](https://github.com/apache/superset/issues/23259)</sup>. To address your issues with legends and categorical colors in deck.gl multi-layer visualizations in Superset, you can use the `CategoricalDeckGLContainer` component. Here's a brief guide: 1. **Define Categories and Colors**: Use the `getCategories` function to define categories and assign colors based on a color scheme or a fixed color. This involves mapping category values to colors using a color function. 2. **Add Colors to Data**: The `addColor` function applies the colors to the data points based on the defined categories. 3. **Toggle and Show Categories**: Implement functions to toggle the visibility of categories and to show a single category, allowing for interactive legend management. 4. **Render the Legend**: Use the `Legend` component to display the categories and enable interaction with them. These steps will help you manage categorical colors and legends effectively in your deck.gl visualizations within Superset <sup>[[2]](https://github.com/apache/superset/blob/master/superset-frontend/plugins/legacy-preset-chart-deckgl/src/CategoricalDeckGLContainer.tsx)</sup><sup>[[3]](https://github.com/apache/superset/blob/master/superset-frontend/plugins/legacy-preset-chart-deckgl/src/factory.tsx)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
