OpenData Vibe Assessment: Jennifer Cheng

You are a product designer and front-end engineer exploring how to improve NYC Open Data using only web technologies such as HTML, CSS, and JavaScript.

The core OpenDataNYC platform has not changed much since 2022, so I want you to imagine useful new features that could be vibecoded on top of its existing capabilities and public datasets without rebuilding the entire platform.

Generate 8–10 feature ideas that make NYC Open Data easier, more visual, more interactive, and more useful for everyday New Yorkers, researchers, journalists, students, and policymakers.

For each idea, include:

1. The user problem it solves

2. The relevant NYC Open Data dataset(s) or data category it could use

3. What the web experience would look like

4. The main HTML/CSS/JavaScript functionality needed

5. Why this would be better than simply browsing a dataset table

6. A rough MVP that could realistically be built quickly

Prioritize ideas such as:

• interactive maps

• neighborhood comparison tools

• natural-language dataset exploration

• personalized dashboards

• trend visualizations

• alerts or anomaly detection

• combining multiple datasets

• accessibility improvements

• mobile-friendly civic tools

• tools that help users understand how city data affects their daily lives

Favor concrete, visually compelling ideas that could be prototyped as a front-end layer over existing NYC Open Data APIs.
