It's . It also allows users to express the results better than tables. Does Python have a ternary conditional operator? Their corresponding pseudocode, i.e., a statement in the English language is also given in these figures. CFG helps us finding independent paths (Cyclomatic Complexity), which leads to the number of test cases required to test the program.We can automate the CFG task using a Python library called pycfg. Hence, data visualization is a simple way to find answers to complicated questions.
