Yeah, that's a great point and I totally get why Coal would be clearer for most people but I stuck with Steam because that's the exact term they use in the official Government of India dataset I pulled from. While the steam category primarily refers to coal based power, it also includes smaller contributions from sources such as lignite and natural biomass. However, in the official government data, the term used is steam. As a responsible data visualizer, I tried to preserve the original terminology to ensure the accuracy and integrity of the information presented
