+Embed the neighborhood graph using Force-directed Graph (`scanpy.tl.draw_graph`)
+================================================================================
+
+For making FDG plots, please use `Scanpy PlotEmbed` with the output of this
+tool and enter "draw_graph_{layout}" as the name of the embedding to plot.
+
+It yields `X_draw_graph_{layout}`, FDG coordinates of data.
