In the domain of data visualization, few charts are as captivating and informative as Sankey diagrams. These diagrams beautifully showcase the flow of something quantifiable from one point to another. Understanding and using Sankey diagrams can elevate our storytelling and provide profound insights into data. In this blog post, we’ll dive into the fascinating world […]

Circle and Star charts in Python
In this post, I share the code on how to create a circle and a star chart using the very flexible XY scatter chart type and the very versatile matplotlib Python library. The number of lines of code needed are very small but the key here is to understand the parametric equations needed to generate […]
Path Navigation Gamification
In an earlier post, I shared a couple of fundamental search and navigation algorithms. You can read it here. In this blog post, I’ll share a fun implementation, a gamification using one of the algorithms. The premise is simple: We have a seeker (depicted by a bandit) whose objective is to find a target (a […]
Stack and Queue Real-time Demo
In this post, I present the concepts of stack and queue which are fundamental in computer science. Furthermore, I demonstrate them with an interactive application below to clearly and visually present what goes on as new elements are added or removed from each and their differences in behavior. The implementation of a stack and queue […]
Pangram Verifier (Python)
Objective Write a script that takes a user-input and checks if it’s a pangram. A pangram is a sentence/phrase/string that contains all letters of the alphabet (in this case, English) at least once. However, technically, a pangram doesn’t necessarily have to be a grammatically correct sentence. The goal of a pangram is to include every […]
Creating a Pangram Phrase with Python
Introduction A pangram is a sentence that contains every letter of the alphabet at least once. The most famous example in English is “The quick brown fox jumps over the lazy dog.” Pangrams are not only fun to create but also useful in various applications, such as testing fonts and keyboards. Technically, a pangram doesn’t […]
Classifying Emails as Spam or Ham Using Naive Bayes
In this blog post, we’ll explore how to use the Naive Bayes algorithm to classify emails as either spam or ham (non-spam). We’ll walk through a Python implementation using the MultinomialNB classifier from the scikit-learn library. This method is particularly effective for text classification problems. Step-by-Step Implementation Importing Libraries: We start by importing the necessary libraries: Loading the Dataset: […]
