Professional Google Earth Visualization

I have an Excel file listing hospitals and clinics across India, and I need that data transformed into a polished Google Earth view. Each placemark should display the facility’s name, full address, and contact information. I’d like every city to have its own color so viewers can immediately see where sites cluster, and the overall map must feel well-organized when zoomed out for a presentation.

Here’s what I’m looking for:
• Import the spreadsheet and create a clean KML/KMZ file.
• Apply distinct colors for each city and a clear legend if space allows.
• Arrange placemarks so labels remain readable and the map layout looks tidy at both city-level and bird’s-eye views.
• Provide one or two high-resolution screenshots that showcase the final layout for slide decks.

Once we start, I’ll share the file plus the final color key. I’m happy to clarify any formatting quirks in the data—just let me know what you need so the end result is visually crisp and presentation-ready.
