Using the CSV module in Python, we can import a CSV file, read it, and extract the data from it, such as the x-axis data and the y-axis data. We can then use matplotlib in order to plot the graph of the extracted data. So what we have to do ...

Step 5: Plot the Graph Plot the graph by passing in the two arrays containing the x and y values retrieved from the CSV file. Customize the line plot by passing in optional values such as line color (color) or line width (lw). Display the finished graph by calling the show method to...

A bar plot is a graph that contains rectangular bars that display the numeric values for categorical feature levels as bars. We will use the bar() method of the pyplot module to plot a bar graph. In the following code, we have read the data from the CSV file using the read_csv() me...
