Write text, get a flow chart, a sequence diagram or a gantt. The chart is inserted in your document, and you can edit its text again afterward. TIPS : - Don't try to add icons, they won't work - Keep the graph positioned in-line in your document, otherwise you won't be able to edit The people without the add-on only see the graphs, but cannot change their content. This is using the mermaid version 10 for rendering https://mermaid.js.org This is ideal for technical documentation, where having up to dates graphs is more important than having pretty graphs. Only editing a few words here and there is very easy with this add-on. Please keep in mind that this add-on is provided for free, i'm not making any money with it. Feel free to leave a review for this add-on so that more people get to use it. Reviews really motivate me to improve the add-on.
