Description
PressViz is a WordPress chart plugin for people who want to publish clear, responsive charts without leaving the block editor.
Most chart tools make you jump between dashboards, embeds, shortcodes, spreadsheets, and third-party services. PressViz keeps the chart workflow inside WordPress: add the PressViz block, enter data manually or upload a CSV, choose a chart type, style it in the sidebar, and publish.

Why WordPress Charts Still Feel Hard
A chart should help a reader understand the story faster. Too often, the workflow gets in the way.
- You leave WordPress to build the chart in another tool
- You paste shortcodes or embeds instead of editing in the post
- Chart data and table data live in separate plugins
- Hosted charts depend on external services, accounts, or scripts
- Canvas-only charts can be hard for screen readers, search engines, and AI crawlers to understand
- Editors inherit charts they are afraid to update later
PressViz is built for a cleaner workflow: chart creation, data editing, visual styling, and front-end rendering all stay connected to the WordPress post.
What You Can Build With PressViz
📊 Charts inside the block editor
Create charts directly in Gutenberg with a native block, guided starter flow, live preview, and sidebar controls.
📁 CSV import and manual data entry
Start from a CSV file, paste numbers into the editable grid, or type values by hand. PressViz is useful for quick editorial charts, reports, comparisons, and data snapshots.
📈 Multiple chart types
Publish bar, line, area, pie, doughnut, scatter, radar, gauge, and funnel charts from one WordPress chart block.
🧾 Chart data that remains part of your site
PressViz stores chart data in your WordPress database using a custom table. You do not need an external chart service, CDN-hosted chart script, or third-party dashboard just to publish one useful chart.
🎨 No-code styling controls
Adjust chart type, title, subtitle, colors, legend, labels, spacing, animation, and responsive behavior without writing code.
📤 Front-end export buttons
Let readers download a chart as a PNG image or export the underlying data as CSV.
Built for SEO, Accessibility, and AI Crawlers
A chart should not become a blank visual shell once it reaches search engines, screen readers, or AI crawlers.
PressViz is designed to make chart output more understandable beyond the canvas. It includes accessible output, screen-reader-friendly data, and structured dataset markup so the chart can carry meaning as content, not just decoration.
That matters for:
- Search engines trying to understand the data behind a chart
- AI crawlers and answer engines reading page context
- Screen reader users who need the data behind the visual
- Publishers who want charts to remain useful, portable, and understandable over time

Why PressViz Is Different
- Block editor native: PressViz is built around the modern WordPress editor, not bolted onto it through old shortcode-era workflows.
- No external chart dashboard: Create, edit, preview, and update charts where you already write.
- Local rendering, no CDN dependency: ECharts is bundled locally, so your charts do not depend on loading a chart library from a third-party CDN.
- Accessible chart output: PressViz includes chart descriptions, semantic output, and screen-reader-friendly data table support.
- SEO-friendly chart metadata: Structured Dataset markup helps make charts more understandable to search engines and AI systems.
- Editor-friendly handoff: Agencies, freelancers, and site builders can hand clients a chart workflow they can keep using after launch.

PressViz is useful for:
- Publishers and editorial teams explaining data inside articles
- Marketers sharing campaign reports, performance summaries, and comparison charts
- Agencies building WordPress sites that clients need to maintain themselves

- Nonprofits, educators, and business teams publishing data snapshots or public reports

FAQ
-
What chart types are supported
-
PressViz currently supports bar, line, area, pie, doughnut, scatter, radar, gauge, and funnel charts.
-
Does PressViz work with the block editor (Gutenberg)
-
Yes. PressViz is built specifically for the WordPress block editor. Creation, editing, data entry, and live preview all happen inside the editor.
-
Can visitors export the charts
-
Yes. You can enable front-end export buttons so visitors can download a chart as a PNG image or export the underlying data as CSV.
-
Will my charts break if I deactivate PressViz
-
If you deactivate the plugin, charts will not render on the front end. Your chart data is preserved in the database and will return when you reactivate. PressViz never deletes your data on deactivation.
-
Does PressViz work on WordPress Multisite
-
Yes, with per-site activation. Activate PressViz on each site where you want to use charts — do not network-activate it. Each site maintains its own chart data and settings independently.
-
Does PressViz add anything to my database
-
Yes. PressViz creates one custom table — `{prefix}pressviz_charts` — to store your chart data. It is created automatically on activation and is never modified by WordPress core or other plugins. On deactivation the table is left intact. It is only removed if you check “Remove Data on Delete” in Settings before deleting the plugin.
