It's Day 8 of the #30DayChartChallenge, and the prompt is "Histogram"

Another #RStats + Observable combination
Kept it simple, but figured out more about small multiples (facets), sorting categories, and colour palettes in Observable today!

NSE-listed companies lost ₹14.3 lakh crore in market capitalisation on Monday. Today’s Number Theory looks at how Trump’s tariff threats — and global retaliation — triggered the selloff, and what past data tells us about such high volatility in the markets.

How global mayhem affected Indian markets

Byline: Sreedev Krishna Kumar

Asian and European stock markets tumbled on Monday amid mounting investor fears of a global recession, driven by intensifying trade tensions sparked by Donald Trump’s tariffs. With major economies showing no signs of backing down, further market volatility is expected. The following charts examine how the crash unfolded and what history tells us about periods of extreme market turbulence.

A bump chart showing GDP ranking changes from 1960-2020 for major economies. China (in bold red) started at 5th place in 1960, dropped to 8th by 1980, began rising after joining the WTO (highlighted in pink), and reached 2nd place by 2020. The US remains consistently in 1st place throughout the period, while Japan and other economies show various ranking changes. GDP values in trillion USD for 2020 are displayed.

Bump chart made with Plotnine in #Python
I'm not totally happy with this one (too many colours and categories), but I figured out some text wrapping and label issues in Plotnine in the process

Bump chart showing the ranking of the top 4 most unequal countries in terms of wealth distribution and how the ranking changes between 2010 and 2023. Peru is currently least equal.

Much has been said about what Trump’s ‘Liberation Day’ tariffs mean for the global liberal order. But what do they mean for everyday American consumers? And what could be its fiscal impact?

Today's Number Theory breaks it down.

What Trump’s tariffs mean for US?

Byline: Sreedev Krishnakumar

The Trump administration’s latest wave of tariffs marks a sharp escalation in U.S. protectionism. Announced on 2 April, the new duties target a wide range of imports and build on years of rising trade barriers. While pitched as a defence of American industry, the immediate fallout will likely be felt by U.S. consumers in the form of higher prices. While increasing imports hurt the US in things such as manufacturing employment, they did usher in an era of cheaper goods. For example, an analysis published in the Wall Street Journal on March 30 said that Chinese imports between 1998 and 2014 in the US brought down inflation for imported goods by 0.6 percentage point lower a year than otherwise. How will the latest tariffs affect the US consumers? Here is what the data shows.

I once again recommend to pull the *.GPX files from your fitness tracker and view them in blender!

Shown is a section of my bike bike commutes (and fun rides around town) form 2022 to today, spanning roughly at least 6000km

You can use this add on I made for that purpose. Even if #b3d is switching to the new extensions platform! Just select "Install from disc..." and you're set.

#30DayChartChallenge Day2 Slope – Google search interest in “How to remove Meta AI from Whatsapp”.

As Meta AI’s chatbot is being rolled out across Europe, many users are wondering how they can turn it off. I found myself googling it too. At the moment, there is no way to deactivate it though, leaving quite a few users upset https://www.huffingtonpost.co.uk/entry/whatsapp-users-react-meta-ai_uk_67e6730ee4b0f69ef1d3351e
