This stacked bar chart shows suicide counts across age groups from 1987 to 2016, revealing how the distribution has shifted over three decades. The visualization uses a dark, categorical color scheme to distinguish six age brackets, with tooltips providing exact counts per segment. It is built with vega-lite-api, vega-lite, and vega, loading data from a CSV file that tracks suicides per 100k population by country, year, sex, and age. The chart encodes year on the y-axis and aggregates the suicide count on the x-axis, with each bar segment colored by age group.
