This line chart shows the number of music releases per genre over time, derived from a JSON dataset of albums and artists. The x-axis displays the release date while the y-axis counts the total releases for each genre. The code processes the data by grouping entries by genre and date, then uses `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` to render the SVG path. The chart is rendered with D3 v5, with axes and labels styled via CSS.
