This stacked bar chart displays categorical spending data from a CSV file, grouping values by year and showing the breakdown of components such as "Função" and "Subfunção" with amounts for "Empenhado" and "Pago". The visualization uses D3 v4’s `d3.stack`, `d3.scaleBand`, and `d3.scaleOrdinal` to render a 460-by-400 pixel SVG, with axes, color-coded segments, and a filter button in the accompanying HTML page.

Fork of D3 Starter

This example shows a minimal D3 version 7 setup where the page displays the text “Hello D3 version 7” in the browser body. It demonstrates the basic import and use of the `select` function from the d3 module to target the body element and set its text content. The code loads the full D3 library from unpkg and bundles the main script as `bundle.js`, with no additional data or complex rendering involved.
