Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of recent attention, adoption, and active maintenance.
This collection of 15 diagram generators turns markdown descriptions into visual maps of systems, cloud topologies, data pipelines, business processes, network layouts, and security models. It helps technical architects, data engineers, business analysts, and security architects see the structure they are describing without leaving their document.
WHO IT'S FOR
Technical Architects

Compatible AgentsThe repository documents support for these agents. The skills may also work with other agents that can load SKILL.md files, but they may need some setup or small changes.
Installs: Only the selected vega skill folder · Claude Code
Before you start
A local repository copy arranged so `skills/<skill-name>` exists relative to the working directory
Run from: Directory containing the `skills/` folder
In a terminal, replace `<skill-name>` with `vega`, keeping the rest of the documented command unchanged, then run it from the directory containing `skills/`.
Installs: Only the selected canvas skill folder · Claude Code

A small dataset as an array of objects or pasted table
The field to use for categories on the x-axis
The numeric field to use on the y-axis
Use the vega skill to turn the supplied small dataset into one clear Vega-Lite bar chart. Return valid JSON inside a `vega-lite` Markdown code fence, include the Vega-Lite v5 `$schema`, preserve the exact field-name casing, and briefly state which fields were mapped to the x and y encodings.
Use the canvas skill to create a compact concept map for the supplied topic and concepts. Return JSON Canvas inside a `canvas` Markdown code fence, use unique node IDs, position nodes on a roughly 100px grid without overlap, and connect only the relationships provided.
Optional notes that should appear beside or over participants
Use the uml skill to create a simple UML sequence diagram for the supplied interaction. Return PlantUML inside a `plantuml` Markdown code fence, begin with `@startuml`, end with `@enduml`, and show the participants and messages in the stated order.
