This visualization shows the number of music releases per year grouped by music genre. It renders a single line chart with a red stroke representing these counts over time, using an SVG canvas of 960x500 pixels. The chart is generated with D3 v5, using functions like `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` to construct the axes, and `line` to create the path. Data from a local `data.json` file is processed in JavaScript to aggregate release dates by genre before being passed to the rendering function.
