This stacked bar chart shows movie genre preferences across five age groups, with each bar segment representing the percentage of respondents who rated a particular movie type. The visualization uses d3.stack() to compute cumulative values and d3.scaleOrdinal with a custom color palette to distinguish categories. Mouse interactions trigger tooltips that display exact percentages, while d3.axisBottom and d3.axisLeft render the axes with gridlines. The data originates from a CSV file, and the chart is rendered as SVG using D3 v7.
