The Basics of Data Visualization
Explore how to create meaningful data visualizations in Rust by using the Poloto crate to generate SVG charts. Learn to handle data from CSV files with Polars, filter out missing values, and present insights visually with themes and custom markers.
We'll cover the following...
Data viz, because we want to see data
Data visualization, or data viz, is much more than filling report pages with eye candy to make it less dull and more dynamic.
We rely heavily on our sight. As such, we process information better when it’s visually interesting. Data is, unfortunately, often very dull to look at.
If we can provide meaningful visual representations of data, we can draw stronger conclusions. The data remains the same, but seeing it on a chart elicits powerful insights and helps us to reason better.
That said, we often associate charts with spreadsheets, and beautiful charts with post-production touch ups, but it doesn’t have to be so. We can accomplish very good results within the Rust ecosystem.
Poloto
Rust provides many crates to help us visualize data. Let’s start with poloto, which is one of the simplest. Poloto ...
