This version turns the organogram into a data-driven web app. The chart, shareholder views, notes and node positions are loaded from editable data rather than being fixed in the markup. You can edit the selected entity in the right-hand panel, save changes in your browser, and export or import the full JSON dataset. Important: this file uses browser-local persistence only. For permanent website-wide saving across users and logins, the same data model must be connected to a backend API and database.
