This example demonstrates the initial step of building a bar chart with D3, where the page loads a CSV file and logs its contents to the browser console. The SVG element remains empty, as the code only fetches and parses the data using `d3.csv` and selects the SVG with `d3.select`. The visualization shows no chart yet, serving as a foundation for subsequent data-binding and shape-rendering code. It uses D3 v5 and renders via SVG, with the data source specified as `data.csv`.
