practice svg
This example shows a simple bar chart of region values using SVG rectangles rendered through D3. The chart displays five data points with regions such as USA, Nigeria, and Ghana, mapping each value to a bar height via d3.scaleLinear and positioning bars with d3.scaleBand. The SVG container is styled with CSS, and the bars are appended dynamically using d3.select and the enter selection pattern, with data bound from a static array. The x-axis uses padding and range rounding for layout.
