Darwin-owned AntV Charts
Darwin-hosted AntV bar, column and line charts. Free rendering with bounded PNG outputs.
Should I use this
Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~2,571Tokens (tool definitions)
~8.4 KBTypical response size
Significant attention impact (2.01% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢generate_bar_chart(data, group, stack, style, theme, ...)
Generate a horizontal bar chart to show data for numerical comparisons among different categories, such as, comparing categorical data and for horizontal comparisons. Hosted by Darwin using AntV's public free renderer. Returns a PNG image. Accepts at most 50 rows with bounded image sizes. No API key is required; payments are not supported.

}🟢generate_column_chart(data, group, stack, style, theme, ...)
Generate a column chart, which are best for comparing categorical data, such as, when values are close, column charts are preferable because our eyes are better at judging height than other visual elements like area or angles.
