# Get a chart image

> Renders a chart as a PNG image. Works for any chart the API key owner can access: charts on dashboards, charts created in chats, and insight charts. The image only includes data the API key owner is allowed to see. Pass chartVersionId to render a specific version; otherwise the latest version is rendered. Rendered images are cached per chart version.

      Chat with the Basedash AI agent about your data. Start a chat by sending a
      message, then continue the conversation with follow-up messages. The
      assistant responds asynchronously: pass the `wait` query parameter to
      receive the finished response in the same request, or poll the assistant
      message (or stream its events) after an HTTP 202. Chats created through
      the API are not shown in the Basedash app.
