This example shows a grouped bar chart comparing viewer ratings for two TV series, Friends and How I Met Your Mother, across ten seasons. The chart uses an SVG container with a fixed width and height, and the data is loaded from a CSV file using d3.csv. The visualization is built with D3 v5 within a React framework, though the primary rendering logic relies on D3’s selection and data-join methods. The bars are not yet drawn in the provided code, as the script only logs the parsed data to the console.
