Documented steps
Run plotting/analysis code with `run_code` (Python) / `runCode` (JS) in an e2b-code-interpreter sandbox (https://e2b.dev/docs/code-interpreting/analyze-data-with-ai)
Inspect `execution.results` — an array of result objects; stdout/stderr live separately in `execution.logs`
For charts/images, check each result for a `.png` field: it contains the image as base64 (e.g. `if (result.png) fs.writeFileSync('chart.png', Buffer.from(result.png, 'base64'))`)
Handle failures via `execution.error` with fields `name`, `value`, `traceback` — a non-null error means the code raised inside the sandbox
Result items can also carry text, tables and other MIME-type renderings of the last expression, so iterate all results rather than assuming one
Known gotchas
The png payload is base64, not raw bytes — decode before writing to disk
Matplotlib charts only appear in results if the code actually renders the figure (e.g. plt.show() or the figure is the cell's last expression); print() output goes to logs, not results
