WHY THIS WORKSHOP
Think About Project Design in a Whole Other Way
D3.js-powered interactive visualizations built from real source documents. A repeatable methodology for any industry. The skills employers are actively hiring for.
01
Ship in Days, Not Months
Every demo in our portfolio was built in a single weekend. The prompting architecture compresses weeks of front-end development into hours. You deploy your first app on day one.
02
Domain Knowledge Is the Moat
Anyone can ask an LLM to make a chart. This teaches you to extract computational primitives from source documents, validate against published data, and build tools that encode real expertise.
03
Fits Into Your Workday
2.5 focused hours per session. No PTO required. Attend over lunch, build alongside the instructor, and be back at your desk by 2:30 PM. Dense, practical, zero filler.
BUILT WITH THIS METHODOLOGY
The Portfolio
Every one of these started as PDFs and a prompting loop. No React. No build step. Single HTML files running real domain logic.

DAY 1 / MONDAY
Document-First Prototyping
- The prompting architecture: extract, structure, confirm, generate
- Feed a real PDF and build a specification-accurate visualization from scratch
- Stack specification: single HTML, vanilla JS, D3.js, configurable constants
- Typography systems, color architecture, and responsive design
- The testing loop: you are Claude's eyes (screenshot, describe, iterate)
- Deploy your first app to a shareable URL by end of day
DAY 2 / TUESDAY
Interactivity + Real Data
- Load real datasets (CSV, JSON, API) into your D3 visualization
- Add filtering, selection, hover states, and drill-down interactions
- Build a scouting-report panel that auto-generates from the data
- Debugging strategies: the CSS-fix story, invisible controls, canvas timing
- Print styles, cross-device testing, and deployment best practices
DAY 3 / WEDNESDAY
Physics + Domain Modeling
- Feed competing academic papers and extract computational primitives
- Analytic vs. numerical equations: know what requires integration
- Implement a governing ODE and validate against published data
- Add collision physics with proper ODE-to-engine handoff
- Prompt for transitions between subsystems (the hardest engineering)
- Mid-trajectory detection, chain reactions, and velocity decomposition
DAY 4 / THURSDAY
Bayesian Inference + Portfolio
- Physics-constrained Bayesian modeling: encode mechanics in the likelihood
- Perturbed-prior Monte Carlo sampling in the browser

FAQ
Common Questions
Do I need to know how to code?
You need basic familiarity with HTML and JavaScript. Enough to know what a function is and how to open a file in a browser. You do not need to be a developer. The entire methodology is about getting Claude to write the code while you provide the domain knowledge and quality control.
What do I need to bring?
A laptop with a browser and a Claude Pro account ($20/month). That is it. No IDE, no local dev environment, no npm. Everything we build is single-file HTML that runs in any browser.
Only 2.5 hours per day. Is that enough?
It is by design. 2.5 focused hours of live building beats 8 hours of lecture and filler. You get 110 minutes of pure instruction per session, plus structured Q&A. That is 10 hours of hands-on building across four days. Most full-day workshops deliver less actual building time after you subtract intros, transitions, and dead time. Every minute here is building.
Are Days 3 and 4 too advanced if I am not a statistician?
Days 3 and 4 introduce every concept from first principles. You do not need prior Bayesian or physics experience. If you can follow the logic of "run the simulation 20 times with slightly different parameters and see where the results land," you will follow the material. The math is in the app, not in your head.
Can I use this for non-sports domains?
Absolutely. The methodology is domain-agnostic. We teach with sports because the data is rich and the problems are visual. Attendees have applied RAP to financial dashboards, supply chain monitoring, clinical trial visualization, and real estate analytics. If you have source documents and a domain, this works.
Will my employer cover this?
Most companies have a professional development or training budget, and this workshop qualifies. It covers D3.js data visualization, AI-assisted development methodology, Bayesian modeling, and interactive application design. These are high-demand skills across every industry. We provide a formal invoice, a W-9, and a detailed syllabus formatted for your manager or L&D team. Many attendees have had this approved under annual training, conference, or tuition reimbursement budgets. If you need a justification letter, email [email protected] and we will send a template you can submit directly.
How does the $300 course credit work?
Every workshop attendee receives a $300 credit applicable to any AthlyticZ course or bundle. This includes the Shiny series (ProductioniZing, CustomiZing WidgetZ, Mobile StructureZ) and the Bayesian series (BayeZian I, BayeZian II). The credit is issued after the workshop and has no expiration date.
What time zone are the sessions in?
All sessions run 12:00 PM to 2:30 PM Eastern Time (9:00 AM to 11:30 AM Pacific). This covers both US coasts during working hours. All sessions are recorded, so if you need to miss a day you can catch up.
Will recordings be available?
Yes. All attendees get 90 days of recording access. But this workshop is designed around live building and real-time debugging. The recordings are a safety net, not a substitute.
What is the refund policy?
Full refund up to 14 days before the workshop. 50% refund up to 7 days before. No refunds within 7 days, but you can transfer your seat to someone else.
Ready to Build?
25 seats per cohort. 4 days. Multiple deployed apps. A methodology you will use for the rest of your career.
