This horizontal bar chart displays vaccination rates across five New York City boroughs, with radio buttons allowing viewers to switch between eight monthly time points from 2021 to 2022. The visualization uses D3 v7 scales and axes to map percentage values from 0 to 100 on the x-axis, with color-coded bars representing each borough. Interactivity is implemented through click event listeners that rebind bar width and label data based on the selected month. The SVG rendering includes background rectangles, axis groups, and text labels showing exact percentages.
