This line chart visualizes weekly YouTube channel analytics, specifically tracking watch time in hours across 52 weeks. The chart uses D3 v7 scaleLinear, line, axisBottom, and axisLeft APIs to render the time-series data. Raw CSV data is fetched from a GitHub gist, parsed, and normalized before being bound to a steelblue line path. The SVG output includes labeled axes for weeks and watch time, with the x-axis formatted to display week numbers.
