This bar chart visualizes the elevations of the 25 highest mountain peaks, using horizontal bars scaled from 14,000 feet upward. The visualization maps mountain names along the y-axis and elevation values along the x-axis, with tick marks and gridlines rendered as SVG elements. It is built with React for component structure and uses D3 v5 APIs including `scaleBand`, `scaleLinear`, `max`, and `csv` to load and process the Mountains_dataset.csv file. The chart applies a steelblue fill to the rectangular marks and an orange stroke for its vertical gridlines.
