This example shows a horizontal bar chart of the elevations of 25 mountain peaks, using the Mountains_dataset.csv. It displays the marks and channels concept with rectangular bars encoding elevation values. The visualization is built with React and D3 v5, using `scaleBand` for the categorical mountain names and `scaleLinear` for the elevation axis. The SVG is rendered with React components, and the chart includes gridlines and axis labels, with a static dataset fetched via `csv`.
