Oh my goodness. I never put that one into "in progress".
We are actively working on the OrgCharts within Linchpin. This happens in three steps:
Step 1: navigation (up, down) through the OrgChart, showing "siblings" within the User Profile. This has already been implemented and shipped with the latest Version.
Step 2: A complete OrgChart as a hub page, not attached to a single person's profile, but attached to the people directory, plus a macro to embed into pages and show specific parts of the chart. This Step is being worked on right now.
Step 3: Organizational OrgCharts that don't depend on the "Superior" field only, but can show e.g. the structure of departments with their respective people. We'll tackle this step towards the end of the year.
