Bar Chart example
This bar chart displays population figures for ten countries, with horizontal bars ordered by country name along the y-axis and population magnitude on the x-axis. The visualization uses D3 v5’s `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data, map values, and render axes, while SVG rectangles encode the bar lengths. Population values are multiplied by 1000 post-import, with tick labels formatted via `format('.3s')` and replacing 'G' with 'B'. Axis gridlines extend across the plotting area, and titles are added as SVG text elements.
