I really try not to write about AI. Too many conversations forced my hand (again)...

Love It, Loathe It, and Lift It: The Missing Conversation on AI

I’ve sat through perhaps too many conversations on AI this month. Whether in-person (hi Outlier), online (oh, the discourse), or anywhere else I happened to be, GenAI is specifically on the m…

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

As we near summer, one of the things I always look forward to are the music festivals! So I've updated my viz "Blues and Jazz Festivals of Canada", showcasing almost 40 festivals across the country...

Thanks Brittany! Actually your approach is more impressive... I thought it would be easier (& efficient). So most days, I just duplicated the dashboard, swapped the chart & revised the title/description.

This is my first election as a Canadian citizen... Are there rules about taking down signs after the election? Barbara Bal signs everywhere...

I love NG... and re: maps, NG is the gold standard! I decided to redo my "Penguins of Antarctica" viz/map and hope I do NG justice...

Feedback always appreciated!

Thanks Brittany! Such a great little technique & I really love how compact the bar chart is.

I thought the vertical labeling was a nice touch... it might be handy or helpful especially if someone starts adding a 3rd or even a 4th bar to the mix... 😉

No idea.😅 It could be a function of greater awareness, improved diagnosis, population growth, changes in school inclusion policies, etc.

Interestingly, if you look at all special education enrollment, about 50% remain unidentified for a specific exceptionality... so the # might be higher

Inspiration came from @brrosenau.bsky.social and her overlapping comparison bars: brittanyrosenau.medium.com/comparison-c...

Can't believe it's almost over... #30DayChartChallenge Day 28 Inclusion

The theme made me think of the special education field... so here's my viz, highlighting the increase in autistic students enrolled in Ontario schools.

Feedback always appreciated!

Inspired and informed by Dinushki De Livera's blog: www.herdata.net/post/transla...

In 2019, the 'Firebird Suite' visualization was created for IronViz, blending music and data through animation and instrument visualization.

#30DayChartChallenge Day 27 Noise

Naturally, I thought of one of my favorite noise rock bands in the 80s & 90s, The Jesus and Mary Chain...

... and decided to visualize the MIDI data of their song, Head On. 🤘

Thanks Kit! I generally use Tableau to do my data visualizations...

You're right... The survey asks about their level (scale of 0-10) of meaning or purpose in life. But in my mind, there might be some overlap, so I was just using it as a proxy for "boredom." I also considered using "loneliness"...
