What this skill does
Generate publication-quality chart images from data.
Chart Image is part of the Messaging & Channels category — messaging and channel skills that connect your agent to chat platforms. You can install it on its own or alongside other messaging & channels skills from the OpenClaw catalog.
How to install Chart Image
The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:
- Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
- Open the in-app Skills panel.
- Search for
chart-imageand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add Chart Image with a single command:
openclaw skills add chart-image
This pulls chart-image from ClawHub and installs it into ~/.openclaw/skills/chart-image/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Chart Image
Once installed, Chart Image activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Turning images into video
Chart Image works with images. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — turns stills into motion — pans and transitions, synced captions, and a vertical export for short-form feeds.
It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.
Manual install (advanced)

chart-image-2.6.35.zipdirectly from our S3 mirror. - Unzip into
~/.openclaw/skills/chart-image/(create the directory if it does not exist). - Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
