What visualization would you pick for a single current value vs a trend?
⚡
Quick Answer
Use Stat or Gauge for a single current value and thresholds; use Time series for trends over time.
Detailed Answer
Stat shows one big number with optional sparkline and color thresholds — good for 'current error rate'. Gauge adds a min/max arc. Time series is for evolution over the window. Table and Bar chart suit top-N breakdowns. Always set a unit and a sensible legend; an unlabeled 1.2k helps no one.

Interview Tip
Always mention setting the unit and legend format.
