The following code sample demonstrates creating a Flowchart activity. This example is from the Fault Handling in a Flowchart Activity Using TryCatch sample.

Flowchart flowChart = new Flowchart
{
    DisplayName = "Promotional Discount Calculation",
    Variables = {discount, promo, numberOfKids},
    StartNode = promoCodeSwitch,
    Nodes = 
    { 
        promoCodeSwitch,
