Data to Chart

Draws a chart from a CSV table and returns it as an image. WHEN TO USE: the user wants to see data as a chart, or needs a chart image for a document, a README, a slide or a chat. HOW IT WORKS: - csv: a header row, then data rows. First column: the category (or x value); the next columns: numbers. Use a comma or semicolon as separator; decimals with a point, or with a comma when the separator is a semicolon. Up to 20,000 characters. - chartType, and what each one needs: bar, horizontalBar, line, area, pie, donut, funnel — one category column + one numeric column; multiline — one x column + one or more numeric columns (one line per column); scatter — two numeric columns (x, y); heatmap — three columns: row, column, value. - title: optional, drawn at the top. RETURNS: - image: a PNG address that IS the chart (rendered on request) — put it straight into Markdown () or an <img>. imageSvg: the same as SVG, sharper where SVG is accepted. Both are null when the CSV is too long to fit in an address; then use svg. - svg: the chart as SVG markup. - link: this tool's web page with the same chart, to edit it. ERRORS say what is wrong with the CSV (missing columns, non-numeric values, too many rows); fix the data and call again. Shows the unified editor inside the conversation. Start with a standalone chart and optionally convert the same table into a carousel without leaving the editor. Charts support up to 500 data rows; converting to slides requires at most 24 rows and may require summarizing the supplied data with the user.

data_to_chart

Exports the supplied current chart as PNG or SVG. Use when the user asks to download the standalone chart. Returns file bytes to the editor and a stateless image URL when the data fit in a link. The link contains the table; nothing is persisted.

export_data_chart

Turns a supplied CSV table into an editable four-slide carousel: cover, chart, a descriptive numerical observation and a closing prompt. Use when the user supplies data and asks for a carousel without writing each slide. At most 24 rows per chart; CSV, semicolon or tab separators. Calculations describe only the supplied data; no causal inference, fact-checking, external data lookup or predicted reach. Title, source, author and square/portrait format are optional. The draft is shown in the editor for review and export. No project is stored.

draft_data_carousel

Shows an editable data carousel in the conversation from 1 to 8 supplied slides. Use for a carousel, visual data story or social slide sequence the user wants to preview, adjust or download. Pass cover, chart and text slides using the provided data and wording; never fabricate data, sources, causal explanations or a viral score. Charts accept at most 24 rows; pie/donut accept up to 8 non-negative categories with a positive total. Source and author are optional and visible on slides. Formats are portrait 1080×1350 and square 1080×1080. Credit to the tool can be disabled. It renders on our manager without storing projects. Links include the complete project, so sharing reveals the data. For a four-slide starting point from CSV, draft_data_carousel computes a descriptive draft.

open_data_chart_editor

Exports the supplied current project as PDF (one page per slide) or ZIP (numbered PNG/SVG files, project JSON, caption and font license). Use only when the user asks to export or download this carousel. No files or projects are persisted. A stateless download URL is returned when it fits in 7,000 characters; otherwise download the file through the editor, which receives its bytes in private UI metadata. The URL includes all project data and is not private. The PDF is rasterized at 1080 pixels wide; SVG files in the ZIP are vectors with embedded Montserrat fonts. User-written claims and sources are not independently verified.
