23bitstudio/teamgraph ? reverse-engineered prompt

Build me a WordPress plugin called TeamGraph that lets me create an org chart and team directory for my company. I want to be able to add people, assign managers, departments, locations, photos, job titles, emails, phone numbers, and profile links, then show that data in three ways, a tree view, a grid view, and a list view, from either a block or a shortcode.

The front end should be simple, fast, and accessible, with the chart built from semantic HTML so it works well with screen readers, phones, and printing, even without JavaScript. On the admin side, I want a clean interface to search and manage team members, drag and drop reporting lines, edit departments and locations, choose brand colors, import and export CSV, and avoid creating manager loops by accident.

Make it feel polished and ready for real use, and if you need current WordPress or build docs, look them up online.
