Tableau | Data analysis | Data storytelling
Sometimes, rarely, real life and vizzing meet and I get to use data visualization outside work. The scenario: We have to refinance our $2.5 million mortgage for our co-operative’s 32-unit building. We have four offers, and want to choose the best option. Dataviz to the rescue!!! – At least, that’s what I thought. What came […]
What you can and cannot say based on the data The smallest unit of a story is the word, and therefore we should be careful with them. We Tableau #datafam folk are data storytellers, we love our tools and pretty vizzes, the nifty tricks that go into making them. We love all that so much, […]
In business life, learning from feedback is what we do. Every day. And when you build tools for others, that involves a process where you ask lots of questions before you start, while you do, and after you do. And then you iterate. Personally, I believe that this is one of the most important skills […]
Continuing on my theme using the steps of critiquing and iterating on an existing chart from Scott Berinato’s book: The original chart: from here: https://www.racfoundation.org/data/uk-pump-prices-over-time 1. What I see first green and black, very close together (is there some significance to petrol being green?), why are we even looking at both? ups and downs, no […]
After a bit of a hiatus during which I concentrated on learning Python and the basics of data visualization in Python, I am back to MakeoverMonday — and maybe, just maybe, I’ll be able to catch up? I just finished reading *Good Charts* by **Scott Berinato**, and want to use the process of critiquing and […]
This week’s MakeoverMonday chart is this one: Source: YouGov Just a quick note: I tried to do everything in 30 minutes, but ended up spending a bit over 60 minutes on it. I knew what I wanted to build and had started building it within the first half hour, but then ended up having to […]

Taking more than a few hours for a viz, spending time to go back and forth on choices like colour palette, size of the dashboard, sourcing data. These things take time. And they are sort of annoying in Tableau, as it’s not indesign or Pagemaker or… Anyway, I can rant, or I can write a […]
The team at MakeoverMonday gives us the above to make over. And I look into the three questions recommended for analysis/makeover: What works? Good colour contrast and legible What does not work so well? weird colour effect on the bars vertical orientation of the y-axis label “BRA” and “CHN” are not super readily recognizable as […]
Storytelling with Data’s January challenge is working with small multiples. I have been seeing these types of visualizations by accomplished Tableau public authors — and have been very intimidated by them myself. So, in the spirit of learning, and going beyond my comfort zone, I have decided to make a visualization using small multiples. But […]
