Altair — Line Chart

Multi-series line chart with point markers and direct end-of-line labels — no separate legend element. Each series uses a status colour token.

Notes

• The chart is one VisualizationSpec with three layered marks: a line, a point, and a filtered text that draws the series name only on the last data point.
• color.scale.range takes resolved DAVE token values, set once per render. Theme toggling re-reads the tokens automatically.
• Vega-Lite’s transform.filter with a JavaScript-style expression is how a single dataset feeds multiple marks at different scopes.
