Summary

Adds a ChartQuery integration: tools, block, icon and generated docs page. I work on ChartQuery, so this PR comes from the ChartQuery team.

Turn data into images with ChartQuery: render any Chart.js v4 chart from its config, describe a chart in plain language and let ChartQuery build it from your data, or generate QR codes and barcodes. Every operation stores the image and returns public links you can put in a message, an email or a document.

Operations:

Create Chart (chartquery_create_chart): Render a Chart.js v4 chart (bar, line, pie, doughnut, radar, scatter and more) from its config and get public links to the image.
Create Chart From Prompt (chartquery_create_chart_from_prompt): Describe a chart in plain language, optionally with raw CSV or JSON data, and get public links to the image ChartQuery builds from it.
Create QR Code (chartquery_create_qr_code): Generate a QR code for a URL, text, email, phone number or Wi-Fi network and get public links to the image.
Create Barcode (chartquery_create_barcode): Generate a barcode (Code 128, EAN-13, UPC-A, ITF-14, Code 39 and more) and get public links to the image.

Every tool sends share: true, so the API answers with JSON links (render_url, view_url, an embed snippet and the expiry) instead of binary image data, which keeps outputs usable by later blocks. Credentials are a ChartQuery API key on the block (AuthMode.ApiKey), sent as the x-api-key header. Every tool is an external ToolConfig.request (POST with a JSON body) against the ChartQuery API. The chart config accepts an object or a JSON string, and the block's code field has a wand that writes a Chart.js config from a description.

Product update (if relevant)

Sim has no chart, QR code or barcode integration today. Workflows can now post a chart of table data to Slack, attach a QR code to an email, or write barcode images back to a product table. The block appears in the integrations catalog under Analytics with 4 templates and grounded skills; the docs page is apps/docs/content/docs/integrations/chartquery.mdx.

Testing

Request bodies and outputs follow the documented OpenAPI request schemas and share: true response of each endpoint. The same endpoints returned share links in live calls from our other integrations; these Sim tools have not been run live from a Sim instance yet.
Local gate on this branch: bun run lint, bun run type-check, bun run check:audits (all 62 audits), bun run apps/sim/scripts/check-canvas-sentences.ts --block=chartquery, and the blocks Vitest suites (85 files, 795 tests) pass. check-block-registry.ts origin/staging could not run locally because my install skipped lifecycle scripts (node_modules/simstudio-ts-sdk missing); the block is new, so no existing subblock id changes.
Regenerated artifacts are committed: tool metadata, docs, block names and the docs manifest.
No new unit tests, following the repo's testing guidance.

Adds ChartQuery tools, block, icon and generated docs: render a Chart.js v4 chart from its config, build a chart from a plain-language description, and create QR codes and barcodes. Every tool asks for share links so the output is a public image URL.

Confidence Score: 4/5

[Medium impact] The new behavior is limited to workflows that choose ChartQuery.

The PR appears safe to merge, with a non-blocking issue that changes surrounding spaces in encoded text.

Findings

Encoded text loses spaces ▶

Summary

Adds ChartQuery with four operations for charts, charts from prompts, QR codes, and barcodes.

ChartQuery actions turn chart and code inputs into shareable image links.
The ChartQuery block gives workflows four ways to make images.
ChartQuery appears in Sim’s integration catalog and docs.

josselinlbe explicitly states that no new unit tests were added, following the repository's testing guidance.

Encoded text loses spaces

chartQueryBody trims every string, including the data sent to QR code and barcode operations. Encoding " hello " sends "hello" instead, so the image contains a different value from the one supplied. Preserve payload strings as given; trim only fields where surrounding spaces are not meaningful.

Suggested change

	body[key] = typeof value === 'string' ? value.trim() : value
	body[key] = value

Fixed, thanks. chartQueryBody no longer trims strings, so a QR code or barcode encodes the value exactly as given. It still leaves out unset optional values (undefined, null, empty string, non-finite numbers) so the API applies its defaults.

          fix(chartquery): send string values as given

Do not trim request strings: spaces can be part of the value a QR code or barcode encodes. Unset optional values are still left out.
