This stacked bar chart visualizes the distribution of top genres among the most popular songs for each year, using data from a public gist. The visualization is implemented with a Vega-Lite specification rendered via the vega-lite-api library, where each bar segment represents a genre’s count. The x-axis lists artists, while the y-axis shows total song counts, colored by genre. The code configures axis styling and tooltips, and the chart automatically fits to the browser window. Dance pop consistently appears as the most frequent genre across the timeline.
