This example shows a bar chart of monthly values from a CSV file, using SVG rectangles positioned along a time-based x-axis and a linear y-axis scaled to the data’s maximum. The code loads data with `csv` from D3 v7, then uses `scaleBand` and `scaleLinear` to map each row to a bar’s position and height. A data join appends `rect` elements to the SVG, relying on the coordinate system’s top-left origin. The chart is styled minimally with CSS, which sets default margins and stroke properties.
