This visualization displays global coal-fired power capacity additions from 2000 to 2024, combining a multi-line time series chart comparing total, China and India, and rest-of-world additions with a bar chart of the top 10 countries by cumulative capacity. Built with React and D3 v7, it uses `scaleLinear`, `scaleTime`, `line`, and `axisBottom` to render the charts, with hover tooltips showing year and megawatt values from the loaded CSV data.
