Jinja for Data Visualization

This section discusses the basic idea of how to visualize data with Jinja. We know that Jinja generates text using a template and data is passed to that template. So we can design Jinja templates to process data and output some text files like HTML or LaTeX or any other text that can be rendered by some software such that it visualizes that data. Here is the description in step-by-step form –

Steps to visualize data with Jinja

Step 1: Decide what software can visualize your data (like a browser, LaTeX engine, etc.) which renders using text.

Step 2: Write a Jinja Template that can process the given data into a text-file/text that can be rendered using your chosen software to visualize the data. Like HTML file for browser.

Step 3: Using a Python program, load the data and then render the Jinja Template with the data to get an output text file.

Step 4: Render the output file on the chosen software to see the visualization of your data. (For example, if it’s an HTML file, render it using browser to see output).

Jinja is a powerful templating engine for rendering text whether it be HTML, LaTeX, or just anything that is just pure text. This article provides an introduction to how to utilize Jinja for Data Visualization. First, it presents the idea and finally provides an example of rendering a simple bar graph on a web page using a Jinja template rendered into HTML with the help of Python programming language. This article assumes basic familiarity with Jinja and Python.
