This 3D bar chart visualizes the number of women in the House of Representatives across nine election years, from 2001 to 2017, split by political party. The chart uses the Highcharts library with the highcharts-3D module, setting an isometric view with a depth projection and groupZPadding to separate the two stacked series. Republican values appear in one stack, while Democratic values appear in another, with the z-axis labeled “Different Parties.” The data is hardcoded as arrays of [x, y] pairs, and the chart’s interactivity and 3D rotation are enabled by Highcharts’ built-in rendering pipeline.
