Chartlet is a lightweight, performance-focused plugin for creating beautiful, interactive charts and graphs via shortcodes.
Stop bloating your database! Unlike other chart plugins that store every graph as a custom post type, Chartlet stores all configurations directly within the shortcode. This makes your site faster and your data easier to manage.
Using the power of Chart.js (loaded locally for maximum privacy and GDPR compliance), Chartlet allows you to visualize data in seconds. Perfect for data journalism, financial reports, or simply adding a professional touch to your blog posts.

Chartlet

The lightest way to create beautiful, responsive charts in WordPress. No database clutter, no heavy libraries — just pure performance.

Henrik Juul-Nyholm

The plugin is an extension to WordPress for importing and integrating responsive visualising SVG data charts from data-diagrams.com. The portal gives access to 33+ different kinds of data charts. The SVG charts are imported into WordPress Media Library to be embedded into the pages in WordPress. Using a subscription with the Free PRO Edition of the plugin, the SVG diagrams are downloaded and embedded into the pages as responsive SVG using Smart Codes: [diagram id=1]
The diagrams are loaded from within WordPress without API calls or iframing to external systems – giving smooth loading with the page flow. When embedded as SVG, the diagrams are loaded with the HTML without delay at all.
Please download the FREE PRO Edition for much better integration of the Editor into the Admin page of the plugin.
Free support by email is provided as part of any subscription starting at only $49.50 USD/year. The “data-diagram.com” link will also disappear from the diagrams when making a subscription.
https://data-diagrams.com is a web portal for easily creating data visualising SVG charts without any programming skills required. Everything is defined through an easy visual user interface. Finally, the designed diagrams are downloaded into WordPress. When data needs updates or the diagram in other ways needs changes, it is easily done through the visual editor.
A model for dynamic live data integration from your own web site is provided. The diagram is produced by XML Stylesheet generating SVG from XML data. Guidance is provided on how to produce the XML data from your inhouse systems (WordPress tables or other tables). When the diagrams needs other updates than data, a new XML Stylesheet (XSL) is produced through the graphical user interface on the portal, and the XSL is replaced onto your own system making it easy to make changes on a day to day basis.
