MapmyIndia Map Example
This example displays an interactive map of India with markers positioned in multiple major cities, including Delhi, Mumbai, Kolkata, and Chennai. The map is built using the MapmyIndia API with a vector layer, and D3.js v7 is used to overlay an SVG circle centered on Delhi with a 10,000-meter radius. The circle’s position updates dynamically on map movement via the `map.on("moveend", update)` event, projecting geographic coordinates to screen space using the `map.project` method. Leaflet, jQuery, and a hardcoded array of latitude-longitude pairs define the marker placements.
