If you want to generate the graph showing the dependencies of your Python modules, try pydeps.
For example, to generate the dependency graph for files in the folder top_github_scraper, I type:
<meta http-equiv="content-type" content="text/html; charset=utf-8">$ pydeps top_github_scraper
The image above is the output of the command.

It can be difficult to understand a confusion matrix, especially when there are many classes in the target. To make your confusion matrix prettier and easier to understand, use pretty_confusion_matrix.
The code is written by wagnerbhbr. I turned this code into a PyPI package so that it can be used by anybody.

If you want to create class diagrams to explain your Python classes, use Mermaid. Mermaid lets you create diagrams and visualizations using text and code.
For example, writing this piece of code on Mermaid Live Editor:
… will create a diagram like above.
Find other diagrams you can create with Mermaid here.

Data drift is unexpected changes in model input data that can lead to model performance degradation. Since your code is built around the characteristics of your data, it is important to detect data drift when it occurs.
Evidently allows you to do exactly in a few lines of Python code. In the code below, I use Evidently to detect changes in feature distribution.
Code to create the report above.

Missing values can sometimes tell you how strongly the presence or absence of one variable affects the presence of another.
To visualize the correlation between different columns based on the missing values, use missingno.dendogram.
The dendrogram uses a hierarchical clustering algorithm to bin variables against one another by their nullity correlation. Cluster leaves which linked together at a distance of zero fully predict one another’s presence.Â
Link to my previous tips on visualization tools in Python.

If you want your manager or colleague to understand your ideas for a project, don’t show them only words or a chunk of code. Use graphs or diagrams.
Imagine you want to explain with your manager the process of training a cat classifier, it would be easier for them to understand the process by showing them a picture like above.
Drawing is also a good way to outline what you want to do before tackling a project.
There are many tools to draw diagrams, but the one I like the most is Excalidraw. In my latest article, I will show you what Excalidraw is and why it is one of the best tools to draw diagrams.

If you want to create a map provided the location in a few lines of code, try folium. Folium is a Python library that allows you to create an interactive map.
You can create an interactive map and add a marker like this with the code above.
View the document of folium here.
I used this library to view the locations of the owners of top machine learning repositories. Pretty cool to see their locations through an interactive map.
