What you can build

  • Turn a CSV of dated measurements into an SVG time-series plot with a UTC x-scale, linear y-scale, and labeled axes.
  • Transform per-period category totals into a stacked-area graphic, using stack layout and area shapes to output SVG paths.
  • Convert geographic coordinates into a projected SVG map, then bind location records to marks for an interactive inspection view.
  • Compare two keyed snapshots of records: use data joins to enter, update, and remove marks, then animate changed values.
  • Convert nested path records into a hierarchy and tree layout, outputting an SVG tree with labeled nodes.

Try this prompt

Build a small browser page that reads a user-selected CSV of dates and measurements without changing the source file. Parse the rows and draw an SVG time-series chart using D3's UTC and linear scales and axes. Report malformed rows clearly. Include sample input and instructions for running the page locally; keep the adaptation small and use documented D3 APIs.

Get started

  1. Add D3 to a JavaScript app

    For a Node-based web app, add the `d3` package with your preferred package manager, then import the namespace or only the symbols you need. The getting-started guide also describes importing submodules.

  2. Create a graphic

    In plain HTML, use the versioned jsDelivr ES module bundle or a locally downloaded UMD bundle. Create an SVG with `d3.create`, configure scales and axes, then append the SVG node to a container.

License & notes

ISCD3 is ISC-licensed and permits use, modification, and distribution with the copyright and permission notice retained. The documented visualization workflows do not require a paid model or API. Browser compute runs on the user's device; using a CDN requires network access, and publishing a web app may incur separate hosting costs. No prices are asserted.

  • D3 is low-level: even a basic chart can take dozens of lines, and the library has no built-in chart abstraction or default presentation.
  • D3 is not a hosted reporting product; the application shell and deployment remain your responsibility.
