How to add Diagrams to a Plone website

Embed Diagrams on Plone

01

Create a Diagrams add-on for Plone on Common Ninja

First, create a Plone Diagrams add-on on Common Ninja. On the add-ons catalog, find the Diagrams and enter the Editor.

02

Save the Diagrams add-on

When you're done creating the Diagrams add-on, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Diagrams Embed Code

When you're ready to add the Diagrams add-on to your Plone website, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the add-on embed code. In the next steps, you will paste this code into your Plone website.

04

Paste the code to your Plone website’s HTML field.

Next, go to your Plone website editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Plone’s editor. Add it to your page, and paste the Diagrams Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Diagrams add-on on your Plone website.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Diagrams add-on on your Plone add-on. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Plone website’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Diagrams add-on to your Plone website. You can do this by putting it straight into your Plone website's HTML code.

Why Use This Widget

Use the Diagrams widget when your ideas involve systems, flows, or relationships that are easier to grasp visually than in text alone. Flow charts, decision trees, and process diagrams help visitors see how pieces connect and what steps lead to which outcomes. This is valuable for onboarding, product architecture, troubleshooting guides, and strategic explanations. Instead of embedding static images that are hard to update, you build and adjust diagrams directly on your site. Clear diagrams reduce misunderstandings, improve learning, and give your documentation or sales content a more professional, thought through feel.
