Real WebGL 3D bar chart, pie chart and data visualization block for WordPress. Import one CSV or JSON — title, labels and values fill the sidebar.

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.

<h4>Free WordPress chart layouts included</h4>
<ul>
<li>Straight column charts for classic category comparisons — optional leader-line annotations on individual bars.</li>
<li>Stacked column charts for totals, grouped values, and composition — optional leader-line annotations on individual segments.</li>
<li>Pie and donut charts for simple shares of a whole.</li>
<li>Line / Area charts for trends, sequences, multi-series data, annotations, point labels, and optional area fills.</li>
<li>Pyramid charts for ranked, proportional, or funnel-like comparisons.</li>
<li>3D stairs pie/donut charts where each segment rises to its own height and forms a stepped 3D ring.</li>
<li>2D and 3D chart views where supported by the selected layout.</li>
<li>Interactive front-end controls with optional legend, sorting, fullscreen view, data table modal, and PNG export.</li>
<li>Responsive chart sections for desktop, tablet, and mobile layouts.</li>
<li>Five block patterns in the Interactive charts category — starter charts with sample data, titles, labels and an editorial card layout you can adapt.</li>
</ul>
<h4>Designed for the WordPress Block Editor</h4>
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.

</ul>
<h4>Bring your own chart data</h4>
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:
<ul>
<li><code>value</code> — the number that drives the chart.</li>
<li><code>headline</code> — the main label, such as a product, country, month, or category.</li>
<li><code>unit</code> — an optional unit such as <code>%</code>, <code>€</code>, <code>kWh</code>, or <code>items</code>.</li>
<li><code>paragraph</code> — optional tooltip text.</li>
<li><code>smallPrint</code> — an optional source note or footnote.</li>
<li><code>color</code> — an optional custom row color such as <code>#ff8800</code>.</li>
<li><code>groupKey</code> — useful for stacked chart groups and multi-series charts.</li>
<li><code>colIndex</code> / <code>rowIndex</code> — optional grid position (column and row index). Legacy header names <code>scatterX</code> / <code>scatterY</code> are still accepted on import.</li>
<li><code>columnLabel</code> / <code>rowLabel</code> — optional category labels for grid rows and columns.</li>
</ul>
A simple CSV can look like this:
<pre><code>value;unit;headline;paragraph;smallPrint
42;%;North;Sales region Q1;Report 2024
31;%;South;Sales region Q1;Report 2024
</code></pre>
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.
<h4>Built for visual data storytelling</h4>
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:
<ul>
<li>editorial data stories</li>
<li>annual reports</li>
<li>landing page sections</li>
<li>product and feature comparisons</li>
<li>survey results</li>
<li>educational content</li>
<li>simple KPI and performance summaries</li>
<li>interactive data sections in WordPress pages and posts</li>
</ul>
<h4>Optional Pro add-on</h4>
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.
