This visualization presents suicide statistics over 30 years, showing the total number of suicides per year as stacked bar segments colored by age group. The chart uses vega-lite-api to define an aggregate transformation on the CSV data source, summing suicides by year and age. The view renders with vega and vega-lite, using a dark configuration for axis styling and a viridis color scheme for age categories, with a tooltip handling from vega-tooltip.
