This bar chart visualizes Mexico’s population by geographic zone, with each bar’s height representing the summed population per zona and bars sorted in descending order. State-level color coding via a category20b scheme and tooltips reveal additional detail. The visualization is built with vega-lite-api, which registers vega and vega-lite, and loads CSV data from a GitHub gist using d3.csv. Custom configuration adjusts axis, title, and label styling, while vega-tooltip provides interactive hover information.
