produces a dynamic widget; it requires a notebook front end and cannot be used in a headless kernel.
▪
Each side is a canvas with its button hidden, so all of that widget's interactions apply: click an empty spot to create a vertex, click or drag a vertex or hyperedge to select or move it, hold Option (Alt) while clicking to extend the selection, press space or to connect the selected vertices into a hyperedge, and right-click for the rename, recolor, and symmetry palette.
"Return"
"e"
▪
Between the two canvases, three buttons act on the drawing: the right-arrow button copies the whole input canvas onto the output canvas; the ellipsis-arrow button appends the vertices and hyperedges currently selected on the input canvas onto the output canvas, without disturbing what is already there; and prints the current input output as a new input cell.

▪
The button below the two canvases evaluates the widget to the drawn input output, the same convention uses for a single hypergraph.
"Return"

▪
accepts all options. They set up the initial input and output hypergraphs when hg1 or hg2 is omitted, but only the input (left) canvas receives them live; the output (right) canvas always opens with default canvas options.
