-Any single line beginning with circuit-schematic: and followed by data (which should be json data, but this
-is not enforced at this level) will be displayed as a circuit schematic. This is simply an input element with
-the value set to the data. It is left to javascript on the page to render that input as a circuit schematic.
-
-ex:
-circuit-schematic:[["r",[128,48,0],{"r":"1","_json_":0},["2","1"]],["view",0,0,2,null,null,null,null,null,null,null],["dc",{"0":0,"1":1,"I(_3)":-1}]]
-
-(This is a schematic with a single one-ohm resistor. Note that this data is not meant to be user-editable.)
