In this video, I explain how to create an advanced #dataviz based on the International Business Communication Standards (#IBCS) using just the native matrix visual in #PowerBI

I believe reaching 200 subscribers is a great achievement for a three weeks old YouTube channel about #PowerBI and #dataviz. However, we're currently at 184. Have you subscribed yet? Have you shared a link to the channel?

What's wrong with the Power BI documentation and default settings?

When is a pie chart a good option?

When is it better to have no pie charts rather than many?

It wasn't a completely lost Saturday. I have first draft version.

Layout, color schema to be adjusted.

A single 1132 rows Vega JSON.

It looks like it's not possible to use color gradient with a color schema, so there will be no gradients on the Sankey diagram, but it's not a critical issue.

I can't even see my own tweets. Twitter is a ransomware.

My Floral Cartogram is in the World #DataVisualization Prize 2023 Poster Long List.

I'll know if I receive any award soon, but a few days I spent to design this #dataviz in #Vega is an award by itself!

Something went wrong with "free speech" on #Twitter. Wrong, but expected. Elon Musk is not "free speech absolutist". He is self-proclimed Emperor of Mars and Asteroid Belt (in his dreams) and a greedy narcissist (in real life).

Read how I built #PowerBI #Deneb #Vega version of the Nightingale’s Rose Diagram and what differences I found between the data driven Vega version and the original. It looks like there were some errors/mistakes/arbitrary #dataviz decision made.

#PowerBI is a powerful BI tool with a strong “back-office” (ETL, data modeling, DAX), but its “front office” (#visualization) has limited capabilities.

#Deneb (certified custom visual for Power BI) and #Vega #VegaLite (data visualization languages), gives you almost endless possibilities.

Read the full article, see examples of Vega charts (with open source code) and an example of a simple but impressive Power BI report with Deneb visual:

I'm still using mostly #Twitter, but if you follow me in Mastodon only, this is what I'm actually tweeting about: powerofbi.org/deneb-vega-data-

My #Vega (#PowerBI #Deneb) data visualizations. A bit more advanced ones than those available on Vega web site. Some of the designs are unique, others are just attempts to reproduce in #Vega (and therefore in #PowerBI) what earlier was created by other #dataviz professionals using other tools.

When someone says "keep <whatever> out of personal opinions and politics" we're not far from the same person staring supporting dictators and writing personal insults. This is why they kindly ask you to do not talk about politics. Deep inside they know they are on the dark side.

Dictatorship fans wish to consume free knowledge shared without 'personal opinions and politics'. They don't understand that our knowledge and ability to share it is backed by our democratic political views.

@jon I'm probably going to oversimplify the problem and exaggerate the cause, but I think an average person is lazy (and even somewhat stupid) and needs TV like media when a person is sitting and absorbing whatever is being aired. And I'm sure Twitter users migrating to Mastodon are looking to follow people they want to follow, not an algorithm that feeds you with whatever the algorithm 'think' you need.
