Histogramme des pépites
This interactive histogram displays the total "nugget" scores for various YouTube channels, with each channel’s bar color-coded by author. The chart uses a grouped bar layout where each channel’s score is broken down by four reviewers, and the y-axis represents the cumulative score. Data from the CSV file is parsed with `d3.csv`, and the visualization is built with `d3.scaleBand` for the x-axis groups and `d3.scaleLinear` for the y-axis, rendered as SVG rectangles within a `<g>` element. The code also calls `d3.axisBottom` and `d3.axisLeft` to label the axes, with styling applied via CSS.
