Probably the worst data visualisation Iโ€™ve seen this month.

Thatโ€™s a double cheeseburger. Thatโ€™s smart.

Colour theory in data visualisation - barbellchart Iโ€™ll take you through a basic explanation of colour theory, how it can be applied to data visualisation, and how you can use it to build an effective colour palette of your own.

Just finished a blog on using colour theory in data visualisation.

I've seen a lot on accessibility, use of colour for categorisation, divergence etc. but I think this plugs a gap.

After - I kid you not - 36 takes (!?), this is now v2, with 83% less muttering, 34% less confusion and 4% less robotic monotone.

Gonna get good at this, or die in the attempt! ๐Ÿคฃ

Took a pic of this last time I was in London. Feels like it belongs here. We Brits are ungrateful shits. Iโ€™m sorry.

While making thousands of people redundant. By SMS. In the middle of the night. After many had relocated and uprooted their lives to return to office.

Meanwhile, Bezos has enough wealth to give each of his employees a $100k share of Amazon and still have $100,000,000,000 for himself.

Finally had a legit business use for a Sankey chart. Fun (albeit time-cosuming!) to build in Tableau.

Neither side, very much. If your 'side' gladly watches Donald Trump abuse his wife, I want no part of it.
Gladly, enough of people for today.

Another calculated dog whistle. Like the Pope meme. In a strange way, I'm more horrified to see Melania abused openly, without comment or care, than the chaos he causes in the world. At least people stand up to that.

Same. Iโ€™m in a pretty good place now but still read his posts every day. I miss Abbey Road. Wish she couldโ€™ve known how much she helped me and countless other people.

Finally seeing that I needed to set that boundary was one of the most painful/crushing realisations I've had. Actually setting it? Probably the most difficult thing I've done as an adult.

This week's Workout Wednesday technical challenge. I found this tough - MUCH prefer prepping data in SQL to trying to model it in Tableau. Felt like I was fighting poor data structure throughout, e.g. using MAKEDATE to get months for the line chart. Just felt... wrong.
