Numerical Computing with Python

Visualizing Online Data

At this point, we have already covered the basics of creating and customizing plots using Matplotlib. In this chapter, we begin the journey of understanding more advanced Matplotlib usage through examples in specialized topics.

When considering the visualization of a concept, the following important factors have to be considered carefully:

• Source of the data
• Filtering and data processing
• Choosing the right plot type for the data:
  • Visualizing the trend of data:
    • Line chart, area chart, and stacked area chart
  • Visualizing univariate distribution:
    • Bar chart, histogram, and kernel density estimation
  • Visualizing bivariate distribution:
    • Scatter plot, KDE density chart, and hexbin chart
  • Visualizing categorical data: ...
