SankeyMATIC is an online Sankey diagram builder created in 2014 by Steve Bogart. Users enter flows in a Source [Amount] Target format and adjust diagrams with interactive controls. Diagrams can be exported as PNG or SVG images, and work can be saved as a plain text file. Data processing happens locally in the browser.
ArrayCat is a browser-based tool for converting strings, lists and CSV columns into PHP, JavaScript, Python, Go, Delphi and Pascal arrays, JSON arrays, MySQL inserts or plain lists. It can remove duplicates, empty items and diacritics, sort lists, change letter case, normalize whitespace and encode Base64. Input is processed in the browser and not uploaded.
The Data Visualisation Catalogue is a project by Severino Ribecca that provides a non-code-based library of information visualization types. The site serves as a learning and inspiration resource, offering a searchable guide to chart methods such as bar charts, heatmaps and treemaps. Example images mostly use dummy data.
Swimlanes.io is a free webapp for making sequence diagrams. Users edit text and the diagram updates in real time. Diagrams can be downloaded as images or shared with a link, and the URL changes whenever the diagram is updated.
PlantUML is an open-source tool that uses simple textual descriptions to draw UML diagrams. It supports diagram types including sequence, use case, class, object, activity, component, deployment, state and timing diagrams, plus non-UML diagrams. Images can be exported in PNG, LaTeX, EPS and SVG.
Terminal Render is a storage, design, or frontend resource for mockups, assets, UI tools, or web search.
ParaView is an open-source, multi-platform data analysis and visualization application built to analyze extremely large datasets using distributed memory computing resources. It runs on Linux, macOS and Windows, from laptops to supercomputers, and includes readers for many file formats and more than 200 filters. It can also run in situ using ParaView Catalyst and in a web browser using trame.
