Author a Scrollytelling Story on a Three-Week Ad-Fraud Anomaly
Overview
What this challenge is about.
Build a scrollytelling page visualizing a three-week ad-fraud anomaly with Svelte and D3, then earn a verifiable certificate.
The scenario
The company sells fraud-measurement software to brands that buy digital advertising through automated marketplaces, and its credibility rests on explaining complex traffic anomalies clearly. A public, well-told account of a real incident is both a trust signal and a lead-generation asset for its marketing team.
The Brief
What you'll do, and what you'll demonstrate.
Turn a technical three-week ad-fraud investigation into a clear, scroll-driven story that a non-expert reader understands and trusts.
Earning criteria — what you'll demonstrate
- Translate a technical incident report into a plain-language narrative for a non-expert audience
- Apply Segel and Heer's narrative-visualization genres to justify a concrete story structure
- Implement performant scroll-driven visualizations that work on both mobile and desktop
- Encode multi-series time data and attribution clearly with D3 so charts serve the story
- Instrument a content page to measure reader scroll-depth and interaction engagement
