The metric component already rendered a big number, a label, and an up/down delta. Now it can carry a trend too. Add a sparkline array and a mini line chart draws in a strip at the bottom of the tile, the ticker look you'd put on a watchlist or a live dashboard.
The line auto-colors red or green by direction, and it respects deltaDirection. So a falling churn metric reads green, not red. Here's the part I like: if you don't set an explicit delta, the tile works out the percentage move from the series' first-to-last change and shows it above the line. One array in, a complete ticker out.
sparkline is an overridable field, so a watchlist tile updates its whole trend on every call:

It's the "Ticker" variant on the metric component page, with a live playground and the exact API request.
