This visualization displays aggregated suicide counts per year, segmented by age group across 30 years of US data. The bar chart uses x-position for year, y-position for the summed suicide counts, and color to distinguish age categories with the 'viridis' color scheme. It leverages the vega-lite-api library, registering vega and vega-lite for rendering, and includes a tooltip handler for interactivity. The data is loaded as TSV from a GitHub URL using d3's tsv parser, with the visualization configured to fit the window size and apply custom axis styling.
