A playground for wild pies
Charts built by someone who pies things.
I'm Justin Grey — pie developer, chart artisan, former NASA (National Association of Snack Artisans) rocket-pie scientist, and recreational pie enthusiast. I go looking for impossible pies to chart. Got one?

Pies That Are Actually Charts
It looks like a pie. It smells like a pie. You cut into it and it's data all the way down. The forbidden dessert.
$42.00
New from the bakery
Pie charts you can actually eat.
Real pies, each one sliced into a different flavor — a pie chart in the most literal, most delicious sense. Every wedge is a data point. Every data point is dessert (or dinner).
The Tasting Flight
One pie, four flavors, plotted clockwise: vanilla cream, blackberry, cherry, and crumble. A pie chart you eat one quadrant at a time. Serve with tea and a spreadsheet.
$33.00
Edible · SavoryThe Savory Quadrant
Flaky chicken pot pie meets a mashed-potato-topped shepherd's wedge. Comfort food, segmented for analysis. Peas and carrots count as outliers.
$36.50
Edible · SavoryThe Comfort Dataset
Beef-and-mushroom pot pie and a mashed-potato shepherd's pie, each wedge a row in the world's most delicious dataset. Rustic crust, statistically significant.
$34.00
Edible · DessertThe Executive Dashboard
Pecan, pumpkin, chocolate, key lime, and a lattice fruit slice with a dollop of whipped margin. Five KPIs, one crust, plated for stakeholders. Spoons provided.

Track Record
Things I've baked, charted, or both.
- Developed Crustpath's pie-slicing AI algorithms.
- Aero-pie-pulsive design for next-generation desserts with NASA's OpenMDePIE.
- Wrote open-source jet-fuel pie software: pyCrust.
- Ate an entire pie at the summit of Mt. Mitchell (11,258 ft of crust).
What I read (and why you should too)
The books that shaped how I think about precision, software, and crust.
- Foundations of Mechanical Flakiness: IYKYN. (If You Know, You Nibble.)
- The Gingery Series on Building Your Own Pie Tins: A bit dated — today we'd do epoxy-granite tins — but still a fascinating zombie-apocalypse dessert-planning guide.
- The best numerical optimization textbook (now with filling): Very mathy. If you want to truly understand how the slices sum to 100%, start here.
- The E-Myth Revisited: Everybody Loves Pies: Work ON your pie business, not IN it. Hear how Sarah turned one pie into a chart of pies into an empire of charts.
