Ritchie S. King

I make charts. I build web applications for exploring them. I write narrative explanations that rely on them.

Previously a staff data visualization engineer at Netflix; before that, eight years in journalism as senior editor for data visualization at FiveThirtyEight, a visual journalist at Quartz, and a science writer and graphics editor at the New York Times. I also wrote a programming textbook called Visual Storytelling with D3.

Eight Years at Netflix

I worked on the data products Netflix’s growth and finance leaders used to run the business — dashboards, explainers, and the shared tools underneath them.

Highlights
  • Launching paid sharing. Built multiple tools tracking our crackdown on password sharing, from a scrollytelling explainer of our detection methodology to the global launch dashboard. Leadership used my applications to choose between competing strategies.
  • Building business tools. Developed dashboards and data for Netflix’s plans and pricing, growth marketing, payments, and growth partnerships. Also contributed to the primary business dashboard, used by thousands of employees.
  • Growing the team. Designed a viz-engineer hiring process other teams adopted, and mentored two new hires into leading launches of their own.
  • Working with agents. Served on an AI task force and helped modernize our development workflows. Ran evals to measure how well AI agents build charts with Netflix’s internal charting library.

Select Interactive Projects

FiveThirtyEight, where I did most of my work in journalism, was not only shut down by ABC News — all the stories and interactive projects were deleted. I’ve rescued some of them from the Internet Archive and republished them here, on my site. They mostly work! (Shoutout Fable 5).

The Atlas of Redistricting

FiveThirtyEight · Jan 2018 · editor

Seven ways to redraw every congressional district in America. I edited this one, coordinating the cartography, data, and design. Had to convince the lone maintainer of an obscure, long-untouched district-drawing app to pull it out of purgatory and update it with the latest Census data.

the scatterplot, before you start hacking

Hack Your Way to Scientific Glory

FiveThirtyEight · Aug 2015

A hands-on demonstration of “p-hacking,” the process by which research scientists make small tweaks to their studies to yield a statistically significant, and thus publishable, result. My colleagues had the idea; I found a suitable research question and backing data sets and designed and built the interactive.

Static Graphics

A pile of charts, maps, and diagrams

Quartz & FiveThirtyEight · 2012–2018

Before the interactives, there were a lot of static graphics: hundreds of them, for stories about jobs reports, hot sauce, hurricanes, the World Cup, and the Supreme Court. The stories were deleted along with the sites. I dug the graphics back out of the Internet Archive and piled them up on one page.
