Three interactive stacked bar charts display total sales from the Shopping Habits Dataset, broken down by states and seasons, states and genders, and seasons and genders. Built with Vega-Lite and embedded via VizHub, each chart uses interactive tooltips and legends to explore aggregated sales totals. The bars are stacked to show component contributions, with color encoding mapping categorical dimensions. The visualizations are rendered declaratively, leveraging Vega-Lite’s JSON specification to compute and display the aggregated data without custom JavaScript.
