What it is
Time Series with Annotations is a clean line chart that lets you mark events on the timeline — launches, incidents, campaigns, holidays. The annotations are first-class, not a hack.
What it does
Single or multi-series line over time with vertical event annotations (label + color), tooltip, cross-filter.
Why use it
Spikes in a time series only mean something with context. Annotations put the context inline.
Three ways teams use it
Product
DAU line with launch annotations.
Marketing
Conversion line with campaign markers.
Ops
Latency with incident annotations.
