Rapid Prototyping with D3 and Observable
The first step to visualizing data is understanding its underlying structure. Instead of starting each project from scratch, let's talk about ways to build a process that speeds up this process, using Observable.
**Amelia Wattenberger ** [@wattenberger](https://observablehq.com/@wattenberger) Amelia Wattenberger is a web developer/designer turned data journalist-engineer at Polygraph (part of The Pudding). She loves creating educational content, whether that's through data essays, interactive blog posts, or Fullstack D3 and Data Visualization. Find her on Twitter at [@wattenberger]() and her work at [wattenberger.com](https://wattenberger.com).

Teaching Visualization Through D3
The D3.js JavaScript library provides a syntax for expressing design choices. In this talk, Michael will draw on his teaching experience to discuss how the challenges of D3.js development enhance the visualization design process. By demanding a nuanced understanding of data structures, and forcing users to articulate their desired visual attributes, D3 helps guide users through intentional design decisions.
**Michael Freeman ** [@mkfreeman](https://observablehq.com/@mkfreeman) Michael Freeman is an Associate Teaching Professor at the University of Washington Information School, where he teaches courses in data visualization, data science, and web development. Prior to his teaching career, he worked as a data visualization specialist and research fellow at the Institute for Health Metrics and Evaluation. He also has a very cute puppy named Aida.
