A stacked bar chart displays global suicide counts aggregated by year and age group over 30 years. The visualization uses the vega-lite-api to create marks, with d3.csv loading the Suicide_Rates_Overview dataset. Age groups are color-encoded via the viridis scale, while tooltips reveal exact suicide numbers per year-age combination. The chart is rendered with Vega, Vega-Lite, and vega-tooltip, with custom styling from a config object improving readability against a dark theme.
