This example uses the general update pattern to create an interactive survey visualization about social conflicts. After the initial render, buttons let users choose between "Republicans," "Democrats," or "Independents," although the data shown is static. The SVG displays grouped horizontal bar charts for four conflict intensity categories (from "Very strong" to "No conflicts") across five social divides (e.g., "Young and Old"). Built with D3 v6, the code manually enters SVG `<rect>` and `<text>` elements for each group without update or exit transitions.
