Exploration. The demo lenses on the live Northwind · Systems Landscape estate. The chart belongs to the lens, not the node — each lens surfaces the metric it cares about (load · data movement · migration pace) on the nodes that matter to it, so switching lenses moves the sparklines to different nodes, and a shared node can show a different feature chart. Containers are lifted at the exact dimensions from the sparklines study (260px compact · 310px chart-beside · 156px mini); shapes run area · bars · line, recoloured by the resolved lens accent.
