   - Check/convert CRS
   - Handle missing values
   - Optimize for rendering

3. Design Visualization
   - Choose basemap tile provider
   - Select visualization type
   - Plan layer composition
   - Design interactions

4. Implement
   - Create GeoDataFrame
   - Build map layers
   - Compose with tiles
   - Add interactivity

5. Optimize & Deploy
   - Test performance
   - Validate accessibility
   - Plan for scaling
   - Deploy/embed
