What it does
D3 Visualization is an agent skill from nexu-io/open-design. Teaches the agent to produce D3 charts and interactive data visualizations. A comprehensive D3.js skill with examples across chart types and techniques giving the agent expert-level knowledge to generate complex, interactive visualizations. Useful for editorial dashboards, reports, data-rich prototypes, and explanatory graphics.
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Data & Analytics, covering Data visualization. It works with D3.js. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Data visualization
Example prompts
- “Use the d3-visualization skill to teach the agent to produce D3 charts and interactive data visualizations”
- “/d3-visualization”
What it can do on your machine
Read from SKILL.md and the folder at commit 53231d4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
D3 Visualization loads about 523 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 147 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

How to use
This catalogue entry advertises the skill in OpenDesign so the agent discovers it during planning. To run the full upstream workflow with its original assets, scripts, and reference documents, install the upstream bundle into your active agent's skills directory:
# Inspect the upstream README for exact paths
open https://github.com/jiannanya/snow-d3/
# Clone or copy the snow-d3/ folder into your workspace's skills/ directory
git clone https://github.com/jiannanya/snow-d3.git skills/snow-d3
Then ask the agent to invoke this skill by name (d3-visualization) or with
one of the trigger phrases listed in this skill's frontmatter, e.g.:
"Create a zoomable treemap for my sales data" "Build a force-directed network graph like example 07 but for my own dataset" "Generate a calendar heatmap in D3"
