Racket makes learning fun...
--- apologies to Fleetwood Mac

I started translating (improving?) the Statistics classes R graphics with Racket plotting and math/distribution.

I had been thinking it would be great to see two different views of the unit circle while floundering around making circular meme-like images. So it is great to find this while searching for general Racket Plot pages:

Plot Animations

There is no specific animation function in the Racket plot package, but animations can be build by repeatedly plotting individual frames onto a canvas or image using `plot/dc`. The technique requires drawing the entire plot every frame, which will be inef...

Sketching is fun!^1 [Remember to (define (draw)...) after (setup)!] Reading a Processing book in order to learn Sketching got me learning radians and polar coordinates.
After ImageMagick and Sketching, I'm back with #RacketPlot, #PolarInterval this time. I've wanted to explore #FlorenceNightingalePlots: #RosePlot #BatWingPlot #CoxcombPlot, for years. I'd like to show Sense/Feeling/Tone ratios for various utterances to explore Bullshit.
Sketching and the Processing books help
I've been re-working a visualization based on lines in #BrettWalker's #ToxicArchipelago. His 1994 data suggested that Japan poured 33x per unit area the over the amount poured by the USA. Down to 17x with recent data!! The code is clunky as as I reacquaint with #RacketPlot and see what I want to do at the same time. After comparing #CementProduction with #LandArea, let's see a Population comparison too. And compare Japan with Germany, and look into Incinerators..

> This table of fisheries data made it easy to appreciate functional programming with sort. You are free to create a function that will.. order.. the data. It's simple to adhere to Howard Wainer's rules for “table construction.”..
> The first rule of table construction is to:
1. Order the rows and columns in a way that makes sense. We are almost never interested in “Austria First.” #HowardWainer

水俣漁業減収1950〜1956

データ表の視覚化で何を気づくかな?「 一本釣漁業」と「囲刺網漁業」はなぜ増えたのかな? カニも54年に増えたみたい(fn:2)。それは生態系の理由か経済的な理由か? カニの天敵が減たやろうか、悪影響が出るまで餌が増えたか、 それか、 遠いところから人がカニを水俣に持って来...
