This bar chart displays the heights of the world’s ten tallest skyscrapers, such as the Burj Khalifa and Shanghai Tower, using a static SVG rendered with D3 version 7. The code creates scales with `d3.scaleBand` and `d3.scaleLinear`, then appends SVG `<rect>` elements for each bar. Axes are drawn using `d3.axisBottom` and `d3.axisLeft`, while mouseover and mouseout events change bar fill colors to red and black. The dataset is hardcoded in JavaScript, with heights in meters.
