One-time app setup (AddLumeo(), CSS & JS) is covered in the

Usage
@using Lumeo <FunnelChart />
Classic marketing funnel tracking visitors through sign-up, trial, qualification, and paid conversion. Each stage label shows the raw count.
B2B sales pipeline from initial leads through proposal, negotiation, and closed-won. Legend hidden to keep the widget compact.
Same conversion funnel with data labels enabled so the exact count is always readable without hovering.
User onboarding journey styled with a warm amber-to-rose gradient palette and toolbox export button.
Shape-aware skeleton with reserved space for legend and axes — no layout shift when real data arrives.
