<p>PressViz is a WordPress chart plugin for people who want to publish clear, responsive charts without leaving the block editor.</p>
<p>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.</p>

<h3>Why WordPress Charts Still Feel Hard</h3>
<p>A chart should help a reader understand the story faster. Too often, the workflow gets in the way.</p>
<ul>
<li>You leave WordPress to build the chart in another tool</li>
<li>You paste shortcodes or embeds instead of editing in the post</li>
<li>Chart data and table data live in separate plugins</li>
<li>Hosted charts depend on external services, accounts, or scripts</li>
<li>Canvas-only charts can be hard for screen readers, search engines, and AI crawlers to understand</li>
<li>Editors inherit charts they are afraid to update later</li>
</ul>
<p>PressViz is built for a cleaner workflow: chart creation, data editing, visual styling, and front-end rendering all stay connected to the WordPress post.</p>
<h3>What You Can Build With PressViz</h3>
<p>📊 <strong>Charts inside the block editor</strong><br />
Create charts directly in Gutenberg with a native block, guided starter flow, live preview, and sidebar controls.</p>
<p>📁 <strong>CSV import and manual data entry</strong><br />
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.</p>
<p>📈 <strong>Multiple chart types</strong><br />
Publish bar, line, area, pie, doughnut, scatter, radar, gauge, and funnel charts from one WordPress chart block.</p>
<p>🧾 <strong>Chart data that remains part of your site</strong><br />
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.</p>
<p>🎨 <strong>No-code styling controls</strong><br />
Adjust chart type, title, subtitle, colors, legend, labels, spacing, animation, and responsive behavior without writing code.</p>
<p>📤 <strong>Front-end export buttons</strong><br />
Let readers download a chart as a PNG image or export the underlying data as CSV.</p>
<h3>Built for SEO, Accessibility, and AI Crawlers</h3>
<p>A chart should not become a blank visual shell once it reaches search engines, screen readers, or AI crawlers.</p>
<p>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.</p>
<p>That matters for:</p>
<ul>
<li>Search engines trying to understand the data behind a chart</li>
<li>AI crawlers and answer engines reading page context</li>
<li>Screen reader users who need the data behind the visual</li>
<li>Publishers who want charts to remain useful, portable, and understandable over time</li>
</ul>

<h3>Why PressViz Is Different</h3>
<ul>
<li><strong>Block editor native:</strong> PressViz is built around the modern WordPress editor, not bolted onto it through old shortcode-era workflows.</li>
<li><strong>No external chart dashboard:</strong> Create, edit, preview, and update charts where you already write.</li>
<li><strong>Local rendering, no CDN dependency:</strong> ECharts is bundled locally, so your charts do not depend on loading a chart library from a third-party CDN.</li>
<li><strong>Accessible chart output:</strong> PressViz includes chart descriptions, semantic output, and screen-reader-friendly data table support.</li>
<li><strong>SEO-friendly chart metadata:</strong> Structured Dataset markup helps make charts more understandable to search engines and AI systems.</li>
<li><strong>Editor-friendly handoff:</strong> Agencies, freelancers, and site builders can hand clients a chart workflow they can keep using after launch.</li>
</ul>
<h3>Who PressViz Is For</h3>
<p>PressViz is useful for:</p>
<ul>

<p>Protovis Loader is a plugin which faciliates the use of <a href="http://vis.stanford.edu/protovis/" rel="nofollow ugc">Protovis</a> scripts. Protovis is a javascript data visualisation library being developed at Stanford, which allows the creation of interactive charts on web pages.</p>
<p>Incorporating Javascript code into WordPress posts can be tricky as it (deliberately) sanitises text typed into posts, which interferes with Javascript. When I first began experimenting with Javascript, this cause me some difficulties, as described in this post. In the end, I decided to roll up my sleeves and write a plugin to make the whole process a lot easier. Protovis Loader was the result.</p>
<p>Protovis Loader makes the whole process a lot easier in two ways:</p>
<ol>
<li>It ships with a copy of the Protovis javascript library and once the plugin is activated, links to the library will automatically be included in page headers.</li>
<li>It creates a shortcode called [pvis] which makes it very easy to include Protovis scripts in blog posts and pages.</li>
</ol>
<p>Usage:</p>
<p>Simply use the [pvis] shortcode in your posts and pages where you want to include a Protovis chart. There are a number of optional parameters:</p>
<ul>
<li>type: ‘chart’ (default) displays a chart in a box with an optional caption, ‘inline’ has no box (e.g. useful for sparklines)</li>
<li>src: path to a Protovis (javascript) code file</li>
<li>height: height of canvas box for the chart</li>
<li>width: width of canvas box for the chart</li>
<li>img: path to a fallback image to use when scripts are blocked or the browser does not support Protovis</li>
<li>alt: alt text for the fallback image</li>
<li>caption: image caption</li>
</ul>
<p>If any content is supplied between the opening [pvis] tag and the closing [/pvis] tag, it is taken to be javascript for inclusion. It may also be interpreted as a caption, but <em>only</em> if a caption field is not supplied and a src field is supplied.</p>
<p>Here is an example of use of the tag:</p>
<p>[pvis src=”http://www.example.com/chart.js” img=”fails.png” height=”125px”]My Caption![/pvis]</p>
<p>You can see the plugin in action on <a href="http://www.stubbornmule.net/resources/protovis-loader/" rel="nofollow ugc">the Stubborn Mule</a>.</p>
<h3>To-Do List</h3>
<p>This list is not really prioritised yet.</p>
<ol>
<li>Improve user-agent (browser) detection</li>
<li>Create an options page</li>
<li>Allow custom CSS files</li>
<li>Allow for alterntive specification of the protovis js library</li>
<li>Replace tags in the imported script to allow shortcode parameters to be used in the script</li>
</ol>
<p>I’m sure there’ll be a lot more!</p>


Protovis Loader

Creates a shortcode to faciliate the use of Protovis data visualization scripts in blog posts.
