This bar chart displays tree heights for different species from an urban trees dataset. Each bar’s height corresponds to the measured height in meters. Built with D3 v7, the visualization loads data from a CSV file using `d3.csv`, maps species to the x-axis with `d3.scaleBand`, and maps heights to the y-axis with `d3.scaleLinear`. The SVG renders bars with a blue fill, rotated x-axis labels, and axes generated via `d3.axisBottom` and `d3.axisLeft`.
