This bar chart displays the number of sides for each named shape in the dataset, with blue bars and value labels atop each bar. The visualization loads CSV data via `d3.csv`, maps names to a `d3.scaleBand` x-axis and side counts to a `d3.scaleLinear` y-axis, then renders rectangles and text labels as SVG elements within a 600x400 viewport. The page includes a summary line showing row and column counts.
