This example demonstrates how to build a basic bar chart using React and D3.js, displaying the heights of six notable buildings from a CSV data file. The SVG-based visualization renders steelblue rectangles for each bar, with text labels sized at 1.4em. The code initializes by selecting the SVG element from the HTML, then loads the data using D3's `csv` function, which parses the building names and heights. The current implementation focuses on data ingestion and console logging, with the visual encoding already defined in the stylesheet.
