Using the same dataset, I’ve shown in my earlier blog: Scattered Data To A Butterfly, Or A Tornado! https://flyingsalmon.net/blog/?p=2194 on how to present similar information visually and add interactivity, in this post, I’ll show other ways to present the information visually and walk through the pros and cons of each. I won’t be using any […]

Scattered Data to a Butterfly, or a Tornado!
What do butterflies and tornadoes have in common? 🙂 Butterfly charts aka Tornado charts are a special type of Bar chart where the data categories are listed vertically instead of the usual horizontal layout. It’s suitable for comparing different variables between two groups (e.g. male/female, apartment/house, car/boat, etc. etc.) and what variables you measure is […]
Organizing raw dataset to creating impactful, interactive visualizations (Excel, PowerBI)
In this post, I’ll walk through the steps starting with a raw dataset that’s organized differently from what I need, to reshaping the data using Excel formulas, and creating an interactive visualization using PowerBI, to publishing it online using PowerBI. Excel and PowerBI work hand-in-hand to solve such problems effectively, and efficiently. First, I’ll start […]

Combining multiple datasets into a single data file (Excel or CSV)

“God” game—revisited (aka Pop game)
What seems like yonks ago, I wrote a fun, DOS based visual game in college that’s a simple simulation of population growth with some user-inputs to the game (i.e. playing “God”, hence the title). You can read about it here. But here, I’m sharing info about that game, revisited, with a different twist. I rewrote […]
Data extraction with multiple criteria with interactive UI
Imagine we are business owners who provide a range of services. We have a large set of customer data but we really want to target those customers who might be interested in your services. We want to extract only that subset of data based on our services. And since we provide multiple, diverse services the […]
A Horse-race Simulation with a “Strip Plot”
Strip plots, or a dot plot horizontally spread out are very useful in certain cases. I’d use it to show spread or concentration of data points across multiple categories. For example, in order to visualize between brand A, and B, what are their product sales (or prices) and where they appear to focus. What the […]
Analyzing 10 Years of Patriots Performance: NFL
Love em or hate em, New England Patriots is a team to reckon with. They’ve implemented numerous creative and suspicious internal strategies that most other teams would love to copy or at least understand. Well, I cannot expose those details as they’re not available anywhere. What is available however is their scores and stats. So, […]
