You can find examples of a Hazard Analysis and Critical Control Point, or HACCP, flow chart on FDA.gov, TCISys.com and Mdsg.umd.edu. These examples vary from a basic to more complex type of flow chart.
A typical HACCP flow chart, also called a flow diagram, with arrows pointing to indicate flow or the next process is on the FDA website. This example shows the flow for the manufacturing of frozen, cooked beef patties.
Maryland Sea Grant's website shows a pasteurized crab meat processing flow chart that includes critical control points. A more complicated example that shows the production of fruited yogurt is on the TCI Systems website.
A HACCP flow chart usually shows the processes that are involved beginning from the receiving of raw materials up to the making, delivery or serving of the end product.
