This tutorial will teach you how to use facet_wrap to create small multiple charts in ggplot2. The small multiple design is an incredibly powerful (and underused) data visualization technique. facet_wrap...continue reading.

This tutorial will show you how to use geom_line to create line charts with ggplot2. Using geom_line is fairly straight forward if you know ggplot2. But if you’re a relative...continue reading.

This tutorial will show you how to use the NumPy sum function (sometimes called np.sum). In the tutorial, I’ll explain what the function does. I’ll also explain the syntax of...continue reading.

This tutorial will show you how to use the NumPy append function (sometimes called np.append). Here, I’ll explain what the function does. I’ll explain the syntax (piece by piece), and...continue reading.

The NumPy linspace function (sometimes called np.linspace) is a tool in Python for creating numeric sequences. It’s somewhat similar to the NumPy arange function, in that it creates sequences of...continue reading.

The Numpy arange function (sometimes called np.arange) is a tool for creating numeric sequences in Python. If you’re learning data science in Python, the Numpy toolkit is important. The NumPy...continue reading.

Let’s talk about the NumPy zeros function. If you’re doing data science in Python, you need to be able to work with numerical data. One of the primary tools for...continue reading.

NumPy arrays are an important component of the Python data science ecosystem. When working with NumPy arrays, you’re going to need to be able to perform basic data manipulation. In...continue reading.

One of the cornerstones of the Python data science ecosystem is NumPy, and the foundation of NumPy is the NumPy array. That being the case, if you want to learn...continue reading.

Linear regression. It’s a technique that almost every data scientist needs to know. Although machine learning and artificial intelligence have developed much more sophisticated techniques, linear regression is still a...continue reading.

The scatter plot … It’s so common that almost everyone knows how to make one in one way or another. You see them in business, academia, media, news. Students use...continue reading.
