This interactive bar chart displays the top five home schools ranked by proposal counts across multiple years, with clickable year buttons (2013–2021) that update the bars to reflect each year’s data. Built with D3 v6, the visualization uses `scaleLinear` and `scaleBand` to position axes, a custom `draw` function to render SVG bars, and click event listeners to switch datasets and highlight the selected year. The chart includes a title, axis labels, and a tooltip behavior on bar hover, while defaulting to 2013 data.
