📈 Background on logo is a searchable catalog of free and open-source (FOSS) data visualization software. With over 700 software packages tagged with capability-specific keywords, it is designed to help analysts, data scientists, and designers use FOSS in their work.

From general-purpose frameworks to specialized libraries for visualizing brain structures, satellite orbits, and electrical grids (to name just a few), is designed to help people find high quality, low-cost visualization resources to support a wide variety of use-cases. We invite you to explore the collection, discover new tools, and help update/maintain listings via GitHub pull request.

🔍 Key features organizes software packages into five categories based on the type of data they visualize: geospatial, network, quantitative, text, and miscellaneous. Tools that span multiple data types are cross-listed under all applicable categories.

Visitors to can explore the entire collection or filter results by data type. Alternatively, they can use the search bar to find visualization authoring tools optimized for a particular programming language, API, chart type, data encoding format, or keyword. Along with software-specific tags, every listing includes:

  1. the name of the tool, along with a link to the tool’s official website/code repository,
  2. a representative image or screenshot to demonstrate the software’s basic output/functionality,
  3. a summary of the tool’s purpose, programming language, and primary capabilities,
  4. the total number of GitHub stars the package has received, as a proxy for popularity in the FOSS community, and
  5. the software license type, for users to determine license compatibility.
