Render a chart inline in the Hermes Desktop transcript: the model emits ::echarts{labels=... values=...} and the plugin mounts an interactive SVG chart (dataZoom slider, click-to-filter legend, resize-aware, 280-560px height clamp) in the plugin SDK's transcript-directive slot.

## Good to know before installing

No network calls, no shell commands, no stored credentials, no environment variables, no background processes, and nothing read or written outside the message it renders; the chart is drawn locally as inline SVG with no third-party libraries.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install echarts-in-chat
```

2. Said no? Turn it on later:

```bash
hermes plugins enable echarts-in-chat
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
