This example shows a real-time line chart animating a stream of normally distributed random data. A smooth basis curve scrolls continuously from the right as new values are generated and appended; the chart shifts left to make room, creating a live monitoring effect. The visualization is built with D3 v5, using `randomNormal` to supply data, `scaleLinear` for axes, and a line generator with `curveBasis`. Animation relies on chained `transition` calls with `easeLinear`, `active`, and `datum` updates inside a recursive `tick` function, rendered as SVG.
