The structure of the data as released and the interactive tool to visualise it are a mess of bad choices that get in the way of helping other analysts derive useful understanding from the data. They could do much better. | policyskeptic

In one of my many 'playing around with map stuff and then posting it on twitter' adventures, I recently posted a kind of comet map - see below. This started off as something completely different but once I had the basic idea I then wondered what kind of data I could apply it to, and that's why I did it to the UK political map of 2019. Read on below for how I did it, as well as how you can replicate it pretty easily in QGIS. Scroll straight to the bottom if you're just looking for the 'how-to'...| Stats, Maps n Pix

Today, our theme is dinosaurs, which made me think about the Datasaurus Dozen! This wild set of datasets is an extension of the famous Anscombe’s Quartet. Despite having completely different-looking distributions when plotted, every single one of the Datasaurus Dozen datasets has the exact same summary statistics. The Datasaurus Dozen is a great reminder for all us data folks to always look beyond summary statistics like the mean and standard deviation to truly understand what’s going on ...| ddanieltan.com
Today’s theme is a data day, so I went over to browse the interesting datasets available from the Asian Development Bank. I found this dataset that shows the inflation levels for Asian countries from 2019 to 2023, with forecasted numbers for 2024 and 2025. As always, I enjoy analysing data from my home region as it’s less widely covered on a global news. So I thought to focus my chart on Southeast asia, in particular, I wanted to highlight the volatile inflation levels experienced by coun...| ddanieltan.com
Weather Today’s theme is Weather and I while searching for inspiration I came across these beautiful wind rose charts from the Lets-Plot gallery.opted for a simple interpretation of showing the changing monthly temperature distribution over a year. Data is taken from a Python version of Forecasting: Principles and Practise. As always, I like to adapt the examples to my home country of Singapore and data for Singapore’s wind readings was provided by Iowa State University’s Iowa Environme...| ddanieltan.com
Today’s theme is Historical and I opted for a simple interpretation of showing the changing monthly temperature distribution over a year. Data is taken from a Python version going through what I consider the best time series textbook, Forecasting: Principles and Practise.

Family For today’s #30DayChartChallenge, the theme is “Family.” I must admit, my mind initially wandered to the Kardashians – but let’s move on from that little embarrassment! I’ve been eager to experiment with Sunburst charts during this challenge. In my opinion, these visually striking charts have a unique ability to convey hierarchical relationships in a captivating way. Fortunately for me, the Python Plotly library comes equipped with a pre-built sunburst module, making my tas...| ddanieltan.com

Today’s theme is Waffle and I would like to create a waffle chart. Waffle charts are excellent for displaying and comparing proportions or part-to-whole relationships within a dataset. They are particularly useful when you want to show how a whole is divided among different categories or segments. However, my visualisation library of choice lets-plot does not have a pre-made “geom” or layer specifically for waffle charts. This means that I have got to get a bit more hands-on to make one...| ddanieltan.com

Time to dust off those old relics from the ancient data catacombs and give them a fresh coat of paint. Today’s lucky candidate?

Note This post is my contribution to this year’s #30DayChartChallenge. Check out my Day 1 post to learn more. Neo Today’s theme is Neo, and since I couldn’t immediately think of an associated chart, I decided to go with my first instinct: create something related to the groundbreaking 1999 movie, The Matrix. I remember watching The Matrix as a kid and being amazed by its mind-bending plot, cool 90s fashion, and fluid action scenes.
