ChartQuill

ChartQuill helps you create clear, accessible charts without leaving the WordPress block editor. Choose one of nine Free chart styles, type or paste spreadsheet data, and publish a responsive visual alongside its title, summary, source, and optional linked data table.

Use purposeful controls for mapping, formatting, colour, and presentation. ChartQuill keeps the data with the block, so every chart remains editable and feels native to the article, report, or page around it.

No iframe, hosted chart service, or front-end CDN is required. Your charts remain editable in WordPress, your data stays under your control, and semantic fallback content keeps the underlying information available beyond the visual.

The free edition includes:

• Vertical and horizontal single-series bar charts.
• Vertical and horizontal grouped bar charts.
• Line charts, scatter plots, histograms, heatmaps, and pie charts.
• Common chart controls for number/date formats, ordering, legends, ticks, chart height, bar spacing/corners, line shape, and point size.
• A guided sample start plus one spreadsheet-like editor with direct CSV/TSV paste, explicit Apply or Cancel actions, and chart-appropriate field mapping.
• Title, accessible summary, source, and unit fields.
• Theme-aware colours, legends, optional grid lines, and context-sensitive labels.
• Readable chart tags that are unique within a post.
• Responsive, self-hosted SVG enhancement without an iframe or chart service.
• One-click linked Chart Data Table blocks with clear connection status, captions, Minimal/Grid/Striped native Block Styles, two densities, standard block styling, and saved snapshots that can outlive their source chart.
• Two opt-in, demo-ready ChartQuill starter patterns; activation never creates demo pages.
• A ChartQuill settings page for the default colour of newly inserted charts.
• Wide and full-width alignment.

Each chart and its data are saved with the post. Titles, summaries, sources, and any linked data table remain available if the visual cannot be rendered, helping the underlying information stay accessible and useful.
