What This Tool Does
Generate modern, professional charts and graphs from data. Supports multiple chart types including bar, line, pie, scatter, doughnut, radar, and more. Features five preset themes for different use cases: Corporate (professional blues and grays), Modern Dark (presentation-ready with vibrant accents), Minimal (publication-quality with subtle colors), Colorful (marketing-friendly with distinct hues), and Academic (colorblind-accessible). Charts can be exported in multiple formats including PNG, SVG, PDF, and WebP. The tool handles custom styling, responsive sizing, gradient fills, data labels, and complex configurations. Perfect for creating data visualizations for reports, presentations, dashboards, social media, and documentation. Returns chart images as signed URLs with configurable expiration or as base64-encoded data for immediate embedding.

Overview
Generate modern, professional charts and graphs from data. Supports 9 chart types (bar, line, pie, doughnut, scatter, bubble, radar, polar area, horizontal bar), 5 preset themes plus custom styling, and 4 export formats (PNG, SVG, PDF, WebP).

Actions
generate_chart
Generate a chart image from structured data with theme and format options.
Required Parameters:
chart_type (string): Type of chart. One of: "bar", "line", "pie", "doughnut", "scatter", "bubble", "radar", "polarArea", "horizontalBar"
data (object): Chart.js compatible data object. Must contain labels (array of strings) and/or datasets (array of dataset objects). Each dataset has label (string), data (array of numbers or point objects), and optional color overrides (backgroundColor, borderColor, borderWidth).
Optional Parameters:
theme (string, default: "corporate"): Preset theme. One of:
"corporate" - Professional blues/grays, white background, top legend. Best for business reports.
"modern_dark" - Dark background (#1E1E1E) with vibrant accent colors, bottom legend. Best for presentations.
"minimal" - Black/white/gray tones, very subtle grid. Best for publications.
"colorful" - Vibrant pink/blue/yellow/teal/purple/orange. Best for marketing and social media.
"academic" - Colorblind-accessible palette (blue, orange, green, purple, brown, gray), black grid. Best for scientific publications.
"custom" - No preset applied; use custom_options to style from scratch.
width (integer, default: 600, range: 100-2000): Chart width in pixels.
height (integer, default: 400, range: 100-2000): Chart height in pixels.
title (string): Chart title text displayed on the chart.
background_color (string, default: "white"): Background color. Accepts named colors ("white", "transparent"), HEX ("#FFFFFF"), RGB ("rgb(255,255,255)"), or HSL.
device_pixel_ratio (integer, default: 1): 1 for normal displays, 2 for retina/high-DPI displays.
custom_options (object): Custom Chart.js options object to override theme defaults. Supports any Chart.js 3.x/4.x option (plugins, scales, etc.).
return_base64 (boolean, default: false): If true, returns base64-encoded image data instead of a file URL. Useful for embedding in emails or immediate display.
store_file (boolean, default: true): If true, stores the chart in cloud storage and returns a signed download URL.
expiration_days (integer, default: 7, range: 1-7): Number of days until the stored file expires and is automatically deleted.
{"action":"generate_chart","chart_type":"pie","data":{"labels":["Desktop","Mobile","Tablet"],"datasets":[{"data":[55,35,10]}]},"title":"Traffic by Device","theme":"colorful"}
Multiple datasets are supported. Theme colors are auto-assigned to datasets that do not specify their own colors.
Workflows
Business Dashboard Chart - Use generate_chart with theme: "corporate", a bar or line chart, and store_file: true to get a signed URL for embedding in reports.
Email-Embedded Chart - Use generate_chart with return_base64: true and store_file: false to get base64 data for inline embedding in emails.
Scientific Publication Figure - Use generate_chart with theme: "academic", output_format: "svg" for scalable vector output suitable for print.
Marketing Infographic - Use generate_chart with theme: "colorful", pie or doughnut chart, and device_pixel_ratio: 2 for high-resolution social media images.
Dark Mode Presentation Slide - Use generate_chart with theme: "modern_dark", large dimensions (1920x1080), and device_pixel_ratio: 2.
Custom Branded Chart - Use theme: "custom" with custom_options to apply your own colors, fonts, grid styles, and legend placement.
Notes
Maximum chart dimensions are 2000x2000 pixels.
Stored files expire after 1-7 days (configurable via expiration_days).
The data object must contain at least a datasets array. The labels array is required for most chart types but not for scatter/bubble charts.
When using theme: "custom", no preset styling is applied. Combine with custom_options for full control.
custom_options merges on top of theme defaults, so you can start with a theme and override specific options.
The device_pixel_ratio: 2 option doubles the rendered resolution (useful for retina displays) but also increases file size.
If both return_base64: true and store_file: true are set, you get both the base64 data and a stored file URL.
Validation: chart_type and data are required for generate_chart. Missing either returns a 400 error.
Recommended sizes: social media 800x600, reports 1000x600, presentations 1920x1080.
