04/07/2023, 1:56 PMI’m trying to generate a new array/table with data about pizza types by percentage. I assume I need to filter pizzaorders based on category or name contains, and then sum all orders by state.

04/07/2023, 1:57 PMI then want to create percentages of each, say, category, by state, so they add up to 100%. I was trying to do this with the extended bar charts.

04/07/2023, 1:57 PMBut then I got distracted because they were just so pretty!

04/07/2023, 1:57 PMI thought a pie chart would be simple to do, but turns out it’s not.

04/07/2023, 1:58 PMI’m looking now at the recent share from @Matt Brodie on data wrangling translations.

Would give a breakdown of % by category

04/07/2023, 2:11 PMI also wonder if some of the existing Plot options might work here (rather than additional wrangling)? Here’s an example where all within Plot, the proportions of male, female and NA penguins (by species) are visualized using

04/07/2023, 2:35 PMOne unrelated question: Do you know what the auto sizing in this chart is showing? It’s an unexpected finding, but I don’t know what it means…! https://observablehq.com/d/2b38352ab79ecae3#cell-300
Tonya Howe
04/07/2023, 2:36 PMIn the specialty category, the size of the dot for NV is larger--and the size of the dot for CA in vegetarian is MUCH larger. What is “auto” showing? I cannot replicate it by choosing any of the other options…

04/07/2023, 2:42 PMah-- I just googled it. Thanks!
Tonya Howe
04/07/2023, 2:44 PMBut why is the specialty dot larger? If the proportion of specialty pizza consumption is the same across states?

04/07/2023, 2:45 PMHere’s what one site says: “If you don’t specify a quantitative scale’s domain, it is the extent (minimum and maximum) of associated channel values, except for the r (radius) scale where it goes from zero to the maximum.”
Tonya Howe
04/07/2023, 2:45 PMI feel like that might be relevant, but I’m not sure.
