Joburg has 12,300 people with assets worth +$1-million, the most of any city in Africa. 3 of the top 10 places with the most millionaires are in the Western Cape: Cape Town (7,400), the Cape Winelands (Stellenbosch) & the Garden Route. 🔗 https://www.theoutlier.co.za/charts/chart/87111

Started reading Capitec: Stalking Giants by TJ Strydom. Interesting to read the history & see how the bank has challenged many unwritten 'rules' of banking. This chart on the closures of ATMs versus Capitec's growth is more evidence of this. https://theoutlier.co.za/charts/chart/88415

Yesterday's newsletter was a special edition: my favourite data visualisation resources. A few years back I started a list of favourite tools and resources. Each year I update the list to add new resources, clear out older/defunct items: theoutlier.co.za/databites/20...

Last working day of the 2024! Was a crazy year in which we published more than 200 new charts in the Our World in Charts collection theoutlier.co.za/charts and launched and ran the first cohort of the African Data Journalism Academy dataacademy.africa We did a lot else but those two stand out.

Fantastic work from @edhawkins.org showyourstripes.info/c/africa/sou...

I'm busy rebuilding our Outlier Insights (and backend Data Desk) tools. V1 done 2 years ago was built on PHP/MySQL. New version will be Supabase/Postgresql, Node, Sveltekit. When it's done we'll have almost entirely off PHP. Love PHP but time to move on.

So agree. And happy to see restaurant/bakery analogies. For a while I've been using a similar example: people need to eat, so in theory restaurants are doing important work. But some serve the homeless and some the rich. Not all will survive, or even deserve to survive.

Kickstarting this feed with an Excel remake of our popular loadshedding calendar: www.youtube.com/watch?v=YHY7... The original is mostly Javascript: loadshed.theoutlier.co.za But someone in a class workshop asked how this could be done in Excel. This is a first stab at that. #datavisualization

New here ... posts to come shortly. Any recommendations for media/data visualisation follows?
