Terms of Use

Flow Chart — TCViz · Effective: September 2026

These Terms of Use govern your use of Flow Chart, a Power BI custom visual developed by TCViz and distributed through Microsoft AppSource. By installing or using the visual you agree to them.

1. Licence tiers

Free tier Free

Available to every Power BI user at no charge, with every feature unlocked:

Data-driven process diagram built from the Levels field wells, with automatic branch merging
Horizontal or vertical layout, per-layer centring and crossing-minimisation
Cycle detection, drawn as discontinuous loops
Dominant path emphasis and top end-to-end variant highlighting
Variants panel with the top 8 paths by value
Collapse and expand branches, with cascading value recalculation
Zoom, native scroll, minimap, in-diagram search and fit to view
KPI badges (value against target, with variation %)
Swimlane bands across the levels
Level images from base64 strings in your model
Native selection, cross-filtering, context menu, standard and report page tooltips
Keyboard focus and high contrast support
The complete Format Pane: layout, nodes, badges, value format, links, swimlanes, legend, data colours

The only limit is size: a Free diagram renders up to 9 nodes, kept as a connected sub-tree from the root so the diagram remains coherent, with a message reporting how many nodes were omitted.

Pro tier Pro

Requires an active AppSource subscription. Identical to Free in every feature, with the node limit removed: the 9-node cap (the Power BI data row limit still applies).
