When this is the right block
- A two-column slope graph showing before/after change for multiple items — lines are automatically colored by direction (up, down, or unchanged) — that is the job of Slope Chart, not a generic content block.
- Use it when you need the editor control labeled “Chart Settings — Title”, which exists on this block’s inspector.
- Inserter grouping: reports, dashboards, and data-heavy pages.
Notes from the implementation
Static block: markup is saved in post content; no PHP render callback in this folder.
