Sol LeWitt Repro
This piece renders ten concentric circles in an SVG, creating an abstract geometric composition inspired by Sol LeWitt. The circles are centered horizontally and anchored at the bottom of the viewport, with their radii increasing in a linear progression. The rendering uses the SVG API directly, creating elements via `document.createElementNS` and setting attributes such as `cx`, `cy`, `r`, and `stroke-width`. The stroke width is proportional to the circle spacing, producing a clean, rule-based visual pattern. The code generates the artwork programmatically without any external data source.
