FiveTech Software tech support forums

We have successfully implemented a phpbb extension to have mermaid diagrams in our forums:

graph TB %% Subgraphs (capas) subgraph subGraph0["Application Layer"] UserApps["User Applications"] Samples["Sample Applications<br/>FiveDBU, PIM, ERP"] end subgraph subGraph1["Framework Layer"] GUI["GUI Framework<br/>TWindow, TDialog, Controls"] Data["Data Management<br/>TXBrowse, TDatabase"] Reports["Document System<br/>TPrinter, TReport, PDF"] Build["Build System<br/>Multi-compiler Support"] end subgraph subGraph2["Core Layer"] Libraries["Core Libraries<br/>FiveH.lib, FiveHC.lib"] Harbour["Harbour/xHarbour Runtime"] WinAPI["Windows API"] end %% Conexiones entre capas UserApps --> GUI UserApps --> Data UserApps --> Reports Samples --> GUI Samples --> Data GUI --> Libraries Data --> Libraries Reports --> Libraries Build --> Libraries Libraries --> Harbour Libraries --> WinAPI

Here you have a free online mermaid diagrams editor that you can use to create them and post them here in the forums:

You can also use AI to create them
