how to plot pie chart using data in pandas-CodePudding

Hi everyone,

I'm relatively new to python. I want to plot a pie chart for department, i.e., how many percent of the employees coming from Sales & Marketing, Operations, Technology, etc...

I'm not sure how to count the total number of employees from respective department first then only fit the data into the pie chart. Any help will be greatly appreciated!

You can use pandas.Series.value_counts with pandas.Series.plot.pie:

df = pd.DataFrame({"department": ["Sales", "Operations", 
                                  "Sales", "Sales", "Technology"]})
df["department"].value_counts().plot.pie()

Output:
