Welcome to episode 16 of Data Viz Today. How can visualizations help people make decisions and set goals? Use a simulation/what-if analysis and visualize the results! Host Alli Torban dives into why simulations are so powerful in persuading people and how to know if your client could benefit from a what-if visualization!

  • 02:15 - Today’s inspired viz “Educate Your Child” by Gabrielle LaMarr LeMee

  • 02:45 - The purpose of her thesis was to explore patterns of segregation in the Chicago school system in order to highlight the systemic and individual choices that create and maintain the problem.

  • 03:15 - Data used: Census data and Chicago Public Schools Data

  • 03:45 - Used R and ArcMap to analyze the data

  • 04:00 - The simulation was first a board game

  • 04:15 - Inspired by Spent interactive simulation

  • 04:25 - Final visualization coded in D3

  • 04:40 - Describing the viz. See it here.

  • 06:15 - She really used the “near-view” by making this simulation about one individual child

  • 06:50 - Benefits of simulations/what-if analysis: no risk, can assess the weaknesses and opportunities quickly, and when you can visualize opportunities, it makes it so much easier to make decisions and to set goals.

  • 07:10 - What do you need to create a what-if analysis? Decide on the factors that you want to vary, the factors you want to see affected, and the formula that combines these factors

  • 07:50 - Examples of what-if analysis: forecasting sales, assessing the impact of increased minimum wage, home buying affordability.

  • 08:55 - What kinds of things should you listen for that would hint that a simulation/what-if analysis would be useful? If you hear a lot of “what if we do this…”, if there’s a big change coming or if you want to propose your own big change, or if you’re in a siutation where it’s impossible or difficult for people to experience someone else’s point of view, or if people are having the same conversation over and over!

  • 09:50 - My inspired viz gives you the opportunity to change various inputs and see how expensive of a house you can afford and when. *I’m not a financial planner - This is for demonstration purposes only. :) Interact with it here.
