This stacked bar chart visualizes associations in Málaga, displaying the sum of activities per association, with bars segmented by thematic category. The chart uses the Vega-Lite API with a `markBar` encoding, mapping quantitative activity sums to the x-axis, association names to the y-axis, and thematic color to the segments. Data is loaded asynchronously from a CSV via `d3.csv`, and the visualization is rendered to SVG through the Vega-Lite API, with customized axis styling for improved readability.
