Data Format
Standard chart types (bar, line, pie, doughnut, radar, polarArea, horizontalBar):
{
"labels": ["Label 1", "Label 2", "Label 3"],
"datasets": [{
"label": "Dataset Name",
"data": [10, 20, 30],

}]
}
Multiple datasets are supported. Theme colors are auto-assigned to datasets that do not specify their own colors.
Workflows
- Business Dashboard Chart - Use
generate_chartwiththeme: "corporate", a bar or line chart, andstore_file: trueto get a signed URL for embedding in reports. - Email-Embedded Chart - Use
generate_chartwithreturn_base64: trueandstore_file: falseto get base64 data for inline embedding in emails. - Scientific Publication Figure - Use
generate_chartwiththeme: "academic",output_format: "svg"for scalable vector output suitable for print. - Marketing Infographic - Use
generate_chartwiththeme: "colorful", pie or doughnut chart, anddevice_pixel_ratio: 2for high-resolution social media images. - Dark Mode Presentation Slide - Use
generate_chartwiththeme: "modern_dark", large dimensions (1920x1080), anddevice_pixel_ratio: 2. - Custom Branded Chart - Use
theme: "custom"withcustom_optionsto 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
dataobject must contain at least adatasetsarray. Thelabelsarray is required for most chart types but not for scatter/bubble charts. - When using
theme: "custom", no preset styling is applied. Combine withcustom_optionsfor full control. custom_optionsmerges on top of theme defaults, so you can start with a theme and override specific options.- The
device_pixel_ratio: 2option doubles the rendered resolution (useful for retina displays) but also increases file size. - If both
return_base64: trueandstore_file: trueare set, you get both the base64 data and a stored file URL. - Validation:
chart_typeanddataare required forgenerate_chart. Missing either returns a 400 error. - Recommended sizes: social media 800x600, reports 1000x600, presentations 1920x1080.
