Triple stroke sparkline
The glow is not a filter over the line, it is THE SAME d drawn three times, at 10, at 5 and at the real width, with falling opacity and blur. And the curve comes from converting Catmull-Rom to cubics: each handle points along the line joining the point's TWO neighbours, which is what makes the line pass through every reading instead of bulging.

How this catalog works
Every component ships with its reproduction prompt: the text you paste into an AI builder to get exactly this piece. The values above are editable, and the prompt you copy carries the ones you chose, so what gets generated is what you were looking at.
