# Plot Graph to Show Ideas - Installation and Scatter Plot

When we do experiments to observe or demonstrate some ideas, one graph can produce a correct intuition if you use a proper graph. For example, if you want to observe the distribution of data, the bar or line graphs are not sufficient to show this information. Because they can only show the average and variance of data. If the data is plotted by the violin or CDF (cumulative distribution function), they will show the distribution of data in a better way.

Of course, how to visualize data is not easy work and I’m not a profession here. I just want to introduce 1) how to plot some general graphs by Python3 (Matplotlib package); 2) these graphs are suited to which situations.

If you know better references, please feel free to send them to me by Email. (zurielibra@gmail.com)

More examples of data visualization can be found on the website of Matplotlib.
