Pop3D Charts – 2D/3D Data Visualizer

Pop3D Charts is a native WordPress chart block for creating interactive 2D and real WebGL 3D charts directly in the Gutenberg editor. Build responsive column charts, stacked charts, pie and donut charts, line/area charts, pyramid charts, and 3D stairs donut charts without shortcodes or an external chart dashboard.

The free plugin is made for visual data storytelling in WordPress: editorial articles, landing pages, reports, comparisons, survey results, educational content, KPI sections, and data-driven pages. Add the block, enter your values, paste spreadsheet data, or import CSV, JSON, XLSX, or XLS files. Then choose a chart layout, adjust the design in the sidebar, and publish an interactive chart that visitors can explore.

Unlike flat chart plugins or CSS-based 3D effects, Pop3D Charts renders its charts in a real WebGL scene using three.js. Where supported by the selected layout, visitors can switch between 2D and 3D views, rotate the chart, inspect the legend, open a semantic data table, and export the chart as a PNG.

Try the free version in WordPress Playground — no install required.

Free WordPress chart layouts included

• Straight column charts for classic category comparisons.
• Stacked column charts for totals, grouped values, and composition.
• Pie and donut charts for simple shares of a whole.
• Line / Area charts for trends, sequences, multi-series data, annotations, point labels, and optional area fills.
• Pyramid charts for ranked, proportional, or funnel-like comparisons.
• 3D stairs pie/donut charts where each segment rises to its own height and forms a stepped 3D ring.
• 2D and 3D chart views where supported by the selected layout.
• Interactive front-end controls with optional legend, sorting, fullscreen view, data table modal, and PNG export.
• Responsive chart sections for desktop, tablet, and mobile layouts.

Designed for the WordPress Block Editor

Everything important happens inside the block sidebar. You can edit rows, import data, switch chart layouts, change palettes, adjust labels, configure captions, and preview the result while you work.

There is no shortcode workflow and no separate proprietary chart database. Chart settings and chart data are stored as normal block attributes inside the post content.

Free version features

• Native Gutenberg chart block for the WordPress Block Editor.
• Real WebGL rendering via three.js for 3D chart scenes.
• Chart layouts: straight columns, stacked columns, pie/donut, Line / Area, Pyramid, and 3D stairs pie/donut.
• Eleven built-in color palettes: Vivid, Ocean Sunset, Purple Raindrops, Spectrum, Magenta Dream, Twilight, Accessible, Material, Corporate, Monochrome, and Diverging.
• Per-row color overrides using hex color values.
• Live editor preview while editing data, labels, appearance, captions, and chart settings.
• Manual row editor for adding, editing, duplicating, reordering, and deleting chart rows.
• Flexible data input: enter rows manually, paste from a spreadsheet, or import JSON, CSV, XLSX, or XLS files — with smart table detection and column mapping for spreadsheet imports.
• Import your chart setup from the file: optional title, subtitle, source note, axis labels and units in CSV or JSON land straight in the block sidebar — pick a layout and you are often ready to publish.
• Chart data export as CSV or JSON, including titles and labels when set.
• Optional front-end controls such as legend, sorting, data table modal, fullscreen view, and PNG download where enabled and supported.
• Lazy loading for 3D scenes when charts scroll into view.
• Built-in translations for English, German, French, and Spanish.
• Accessibility-minded output with labelled chart regions, semantic data tables, keyboard-friendly dialogs, accessible toolbar labels, and live regions for loading and tooltip states.

Bring your own chart data

Start with a few manual rows, paste values from Excel or Google Sheets, or import a prepared file. You can put chart title, description, source, axis names and units in the same file above the data table — on import they appear in the sidebar tabs so you rarely need to type them by hand. Pick the chart layout that fits your story; scales, tick labels and row links from the file are applied too. Re-importing always replaces the previous chart so nothing stale is left behind.

The importer finds the data table even when extra lines appear above it, maps common column names automatically, and lets you assign columns manually when needed.

For most charts, the most useful columns are:

• value — the number that drives the chart.
• headline — the main label, such as a product, country, month, or category.
• unit — an optional unit such as %, €, kWh, or items.
• paragraph — optional tooltip text.
• smallPrint — an optional source note or footnote.
• color — an optional custom row color such as #ff8800.
• groupKey — useful for stacked chart groups and multi-series charts.
• colIndex / rowIndex — optional grid position (column and row index). Legacy header names scatterX / scatterY are still accepted on import.
• columnLabel / rowLabel — optional category labels for grid rows and columns.

A simple CSV can look like this:

Tip: create one chart manually, then export it as CSV from the block settings. The exported file gives you a practical template — complete with title, labels and units you can reuse in your own spreadsheet.

Built for visual data storytelling

Pop3D Charts is made for charts that feel like part of the page instead of external reports embedded into it. Use it when a standard flat chart feels too plain and you want a more visual, interactive, and slightly fancy way to present your data.

It works especially well for:

• editorial data stories
• annual reports
• landing page sections
• product and feature comparisons
• survey results
• educational content
• simple KPI and performance summaries
• interactive data sections in WordPress pages and posts

Optional Pro add-on

The free plugin is fully usable on its own. An optional Pro add-on is available separately outside the WordPress.org directory and extends the same Gutenberg chart block with additional layouts, palettes, styling options, and ready-made chart patterns.

The free version includes straight columns, stacked columns, pie/donut, line/area, pyramid, and 3D stairs pie/donut charts, plus import/export, built-in palettes, 2D/3D views where supported, and optional front-end controls.

Pro is only needed if you want more advanced chart layouts, extra design options, and ready-made chart patterns.
