This example demonstrates the fundamental steps of creating a bar chart with D3.js, starting with selecting an SVG element and loading data from a CSV file. The code uses `d3.select` to grab the SVG and `d3.csv` to asynchronously fetch `data.csv`, logging the parsed data to the console. It sets the chart’s dimensions by reading the SVG’s width and height attributes. While the current implementation only loads and logs the data, it establishes the scaffolding for binding that data to visual bars, relying on D3 v5’s data-join and SVG rendering capabilities.
