Overview of this book

Python Data Visualization Cookbook will progress the reader from the point of installing and setting up a Python environment for data manipulation and visualization all the way to 3D animations using Python libraries. Readers will benefit from over 60 precise and reproducible recipes that will guide the reader towards a better understanding of data concepts and the building blocks for subsequent and sometimes more advanced concepts. Python Data Visualization Cookbook starts by showing how to set up matplotlib and the related libraries that are required for most parts of the book, before moving on to discuss some of the lesser-used diagrams and charts such as Gantt Charts or Sankey diagrams. Initially it uses simple plots and charts to more advanced ones, to make it easy to understand for readers. As the readers will go through the book, they will get to know about the 3D diagrams and animations. Maps are irreplaceable for displaying geo-spatial data, so this book will also show how to build them. In the last chapter, it includes explanation on how to incorporate matplotlib into different environments, such as a writing system, LaTeX, or how to create Gantt charts using Python.

Importing data from CSV

In this recipe, we'll work with the most common file format that you will encounter in the wild world of data—CSV. It stands for Comma Separated Values, which almost explains all the formatting there is. (There is also a header part of the file, but those values are also comma separated.)

Python has a module called csv that supports reading and writing CSV files in various dialects. Dialects are important because there is no standard CSV, and different applications implement CSV in slightly different ways. A file's dialect is almost always recognizable by the first look into the file.

Getting ready

What we need for this recipe is the CSV file itself. We'll use sample CSV data that you can download from ch02-data.csv.

We assume that sample data files are in the same folder as the code reading them.

How to do it...

The following code example demonstrates how to import data from a CSV file. We will perform the following steps for this:

  1. Open the ch02-data...
