Creating a half-circle and a rainbow chart
In this blog, I demonstrate creating a half-circle, and then a rainbow chart in Excel using data. The charts are dynamic and fully customizable. Other than just being pretty, they have plenty of uses (e.g. for seating arrangements in an arena, for showing counts of seats occupied by different parties, and much more. Besides, they’re […]
Altitudes Above Earth
Welcome to an exciting and educational view of the skies above us. In this blog, we’ll look at various altitudes where some of the most interesting objects and phenomena can be found. From the gentle drift of hot air balloons and the majestic flight of vultures to the high-speed travel of jet planes and the […]
Interesting Facts at Ocean Depths
Exploring the depths of the ocean reveals a fascinating world teeming with diverse marine life and remarkable human achievements and adventures.In this chart, we look at some of the usual depths inhabited by various marine creatures, from the shallow waters to the abyssal plains and down to the deepest seabed on Earth.Additionally, I highlight some […]
Creating an Analog Clock in Excel
Welcome back! In this post, I demonstrate creating an analog clock as a chart in Excel that’s completely data-driven, and even real-time. The clock, created as a scatter plot in Excel is dynamic, scalable, accurate, and highly customizable. You will discover the way to generate such a chart that updates the clock visual according to […]
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 […]
Search Algorithms and Path Navigation
In this post, I introduce two fundamental search algorithms used to traverse or search through graphs or tree data structures: breadth-first search (BFS), and depth-first search (DFS). I also present an overview of a path/search navigation scripts for both algorithms and compare their metrics. This post builds on my earlier post about stack and queue […]
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 […]
