This data visualization shows a map of India with temperature data for countries around the world, using a color scale that ranges from blue for cold to red for hot. India is highlighted in orange with its internal state boundaries drawn as black lines, while other countries appear with reduced opacity and show temperature values on hover through a tooltip. The visualization combines multiple D3 components including `d3.geoPath` for map projection, `d3.scaleSequential` for the temperature color ramp, and `d3.zoom` for interactive pan and zoom functionality. World country data comes from the world-atlas TopoJSON file, while India's state boundaries are fetched from a separate GeoJSON source.
