This stacked bar chart visualizes global suicide rates over 30 years, grouped by age, using aggregated counts per year. The visualization encodes age categories as colors and uses the y-axis for time, with bar size reflecting the number of cases. It is built with the vega-lite-api, which wraps Vega-Lite and Vega, and loads CSV data via d3.csv. The chart features a custom color scale and tooltips to show aggregated counts for each age group.
