This pull request was created as a result of the following prompt from Copilot chat.

Overlay shortened names (abbreviations) of all Indian states onto the provided Polity Map of India (image1). Each state's abbreviation should be placed approximately at the center of its region. The text color for the abbreviations should be white for clear visibility against the blue map background. Example abbreviations: UP for Uttar Pradesh, MH for Maharashtra, RJ for Rajasthan, etc. Ensure the map remains neat and readable, and export the updated map as a PNG file, placing it in the repository (e.g., assets or images folder).
