Data visualization with Python and Matplotlib – Part 2

In the previous chapter I described how to import the needed data to Pandas DataFrames, and how to manipulate DataFrame object. Now lets take a look on how we can visualize that data in a plot form. This is by no means a proper analysis of the suicide rates. It is a plotting example.
Below are the necessary imports. ‘%matplotlib inline’ is IPython-specific directive which displays matplotlib plots in notebook. It can be removed and plt.show() can be added to the end of the code to display the plot. We are also importing numpy, pandas, matplotlib.pyplot for plotting, and separately matplotlib to work on specific matplotlib functions if needed.

In [1]:
%matplotlib inline
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import matplotlib as mpl

Next step is to import our data and assign it to DataFrame. We created that table in the previous example.

In [2]:
table = pd.read_excel('mergedData.xlsx')
table.head()

Data import with Python, using pandas DataFrame – Part 1

World Health Organization provides a wide range of data available for download in different formats.
The data is accessible through their website: http://www.who.int/gho/en/
In this example we will be working with Pandas DataFrame to organize the data. As an example I am going to work on suicide rates throughout the world.

In [1]:
import pandas as pd

By using ‘read_csv’ function, suicide crude rates (per 100,000 people) data is assigned to pandas object.

In [2]:
suicideData = pd.read_csv('SuicBoth.csv')
suicideData.head()
Out[2]:

Importing CSV data in Python

One of the purposes of this blog, as it is stated in the About page, is to share useful information while I am practicing to code. I think it is also a good habit to have posts like this one to refresh my own memory. Data comes in many forms (including CSV – Comma-separated values), and it needs to be imported for further manipulations and analyses.
