However, sometimes we also want to include the value that is left behind.

Which makes them look different from the traditional funnels that are used in, for example, Sales or Marketing departments.\n\nThis notebook allows the user to create a vertical Sankeys, using their own data (check below the graph to paste your numbers!).\n\nBased on the wonderful notebooks from [Kamil Essekkat](/@ekamil/flow-o-matic) and [Tom Shanley](/@tomshanley/vertical-sankey-with-elegant-links-to-entry-and-exit-nodes)`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":3,"value":"$30","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":482,"value":"md` ## Data\n\nThis Sankey is displaying fake data right now.
