31:T2229,# Plot Twist, September 2022 *Plot Twist* is the newsletter about [Observable Plot](https://observablehq.com/plot?utm_campaign=plotpromo&utm_source=newsletter). Every month or so, we highlight the inspiring work being done in Observable Plot by creators from our growing user community. We also provide development updates, showcase new features, and share examples and best practices. --- # Winners of Tour de France Observable user PAC2 is charting the stage winners of Tour de France by flag, with data from Wikidata, “collected using a SPARQL query and imported directly into Observable.” [

](https://observablehq.com/@pac02/all-tour-de-frances-stage-winners-by-country-of-citizenship?&utm_source=newsletter) Check out the visualization, and the glorious SPARQL query that powers it. --- # NBA Power Rankings [

](https://observablehq.com/@nor/nba-power-rankings?&utm_source=newsletter) Nicholas Ortenzio, who has shared [quite a lot of NBA visualizations](https://observablehq.com/collection/@nor/nba) on Observable created this chart of Power Rankings, for each week of the 2021-22 regular season. “Viewing the entire league for all 25 weeks creates a very busy chart, so I have added various options for filtering.” See the notebook --- # Golf - Career Earnings (1983-2016) Another sports-related notebook: Golf - Career Earnings (1983-2016), by [Ajay](https://observablehq.com/@stroked), follows the money. [ Golf Career Earnings

](https://observablehq.com/@stroked/golf-career-earnings?utm_campaign=plotpromo&utm_source=newsletter) A modest line chart, animated with Observable Inputs. To double down on golf, also check Ajay’s [Golf driving distance](https://observablehq.com/@stroked/golf-driving-distance) notebook, which shows how much the sport has changed between 1995 and 2005. Investigate Career Earnings --- # UN Population Projections [

](https://observablehq.com/@herbps10/un-population-projections-2022?utm_campaign=plotpromo&utm_source=newsletter) In this notebook Herb Susmann, graduate student in Biostatistics at UMass Amherst, shows the estimations made by the United Nations Population Division in its recently released World Population Prospects 2022. The interactive notebook allows us to see the expected scenario for each country, from present up to 2100. See Projections --- # Plot 0.6 [ Plot 06

](https://github.com/observablehq/plot/blob/main/CHANGELOG.md#060) A new version of Plot has been released, which now includes JSDoc comments from the README in the unminified bundle—allowing inline documentation in code development environments such as VSCode (and soon, directly in Observable!). See Plot 0.6’s release notes --- # The Kings Problem The Kings Problem asks: “How many ways are there to place some number of non-attacking kings on a chessboard?” [

](https://observablehq.com/@mcmcclur/the-kings-problem?utm_campaign=plotpromo&utm_source=newsletter) The animation produced by Mark McClure shows “some randomly generated boards with non-attacking kings. Each board is generated via a random walk through a graph that can be used to prove that the answer to the Kings Problem is 1,355,115,601.” Check out the notebook --- # Data to practice with [

](https://observablehq.com/collection/@observablehq/datasets?utm_campaign=plotpromo&utm_source=newsletter) Need some data to hone your Plot skills? Our new collection of [curated datasets](https://observablehq.com/collection/@observablehq/datasets?utm_campaign=plotpromo&utm_source=newsletter) was created to be comprehensive and real, yet simple and friendly. Ideal for learning, teaching and web-based demonstration of data analysis and visualization. Learn about curated datasets --- ## Upcoming Events & Learning Opportunities 📅

Here’s the description (and [check out the teaser video!](https://frontendmasters.com/courses/data-visualization/)) > _Instead of staring at spreadsheets of data, you can turn that data into something visual and interactive! It allows you to explore and answer questions about the information quickly. In the course, you’ll build hands-on projects with the Observable Plot library. You’ll make visualizations or “plots,” add interactivity and embed your plots around the web with JavaScript and frameworks like React. By learning these fundamentals, you’ll be able to have what you need to move on to more complex work with d3.js and beyond!_ This course and others like it are available as part of the Frontend Masters video subscription.
