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. The people without the addon only see the graphs but cannot change their content. This is using the mermaidJS 8.5.1 for rendering https://mermaidjs.github.io/ 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 addon. Please keep in mind that this addon is provided for free, i'm not making any money with it. Feel free to leave a review for this addon so that more people get to use it. Review really motivate me to improve the addon. The next feature i'd like to implement is theming, for now only 4 default themes are available. The app now uses the latest version of mermaid by default, so it it crashes (because of an update of mermaid) please contact me on my personal email, renan.lecaro@gmail.com
