FAQPage Schema
How do I add accessible inline SVG charts to my MDX blog posts?

To add accessible inline SVG charts to MDX blog posts, provide a chart request with type and data. The system enforces accessibility using role=img, aria-label, title, and desc tags, rendering dark-mode-compatible visualizations directly within your article content.

What chart types are supported for data visualization in dark mode blogs?

Supported chart types for dark mode blogs include horizontal bar, grouped bar, donut, line, lollipop, area, and radar charts. Each visualization renders with transparent backgrounds and a standard SVG shell, ensuring consistent styling across both HTML and JSX/MDX outputs.

Can I use these SVG charts in both HTML and JSX outputs?

Yes, these SVG charts automatically adapt for both HTML and JSX/MDX outputs. The system detects your blog format and applies a standard SVG shell with transparent backgrounds, ensuring consistent rendering across different publishing platforms without manual code adjustments.

How does the system detect chart-worthy data during blog writing?

During blog-write and blog-rewrite workflows, the system automatically identifies chart-worthy data within your article text. When detected, it generates appropriate inline SVG visualizations, making it suitable for data-driven articles, dashboards, and visual sidebars without manual chart creation.

Do I need external libraries to render SVG charts in my blog?

No external libraries are required. The system generates self-contained inline SVG code with accessible markup and transparent backgrounds, meaning the charts render natively in the browser without depending on client-side JavaScript charting libraries or external rendering engines.
