 Integrate with [[https://ngspice.sourceforge.io/][ngspice]], [[http://www.bwsst.com/][SPICE]], or a similar electronics circuit
 simulator, enabling interactive circuit design and simulation in 3D.
 
+A circuit designer using ngspice could place resistors/capacitors in
+3D space, connect them with virtual wires, and simultaneously
+visualize current flow as animated particles while overlaying
+Pandas-generated performance metrics. This eliminates
+context-switching between tools - data, simulation, and visualization
+coexist in one spatial workflow.
+
+This would provide contextual continuity. Related tools (e.g., a
+simulation and its data analysis) can be spatially adjacent in space,
+avoiding the "window-switching" friction of 2D desktops.
+
+** 3D visualization of statistical data
+
+Dataframes from Pandas would render as 3D grids where rows/columns
+occupy spatial axes. Dragging a region of the grid would instantly
+filter related data. Unlike 2D tables where multidimensional
+relationships are flattened, 3D preserves natural spatial
+relationships- e.g., high-value data points "tower" above low-value
+ones, creating intuitive topographical insights.
+
+A 3D scatter plot shows all variables simultaneously; rotating it
+reveals patterns invisible in 2D projections.
+
+Students could "walk through" a dataset experiencing trends as spatial
+terrain rather than abstract graphs.
