Project Plan: FBI Crime Data Explorer - Interactive Onboarding Tutorial System

Executive Summary

This project aims to create a modern, interactive tutorial/onboarding system for the FBI's Crime Data Explorer (CDE) website, inspired by mobile game onboarding patterns (like Pokémon GO) adapted for web applications. The goal is to help new users progressively learn the platform's features through guided, contextual tutorials.

Current Technology Analysis

Based on the FBI CDE website structure, the current implementation appears to use:

Current Stack (Observed):

  • Frontend Framework: Likely a JavaScript SPA (Single Page Application) architecture
  • Styling: Custom CSS with government design system influences (USWDS - U.S. Web Design System patterns)
  • Data Visualization: D3.js or similar charting libraries for crime statistics
  • API: RESTful APIs serving crime data from the UCR (Uniform Crime Reporting) Program
  • Hosting: Government cloud infrastructure (.gov domain with CJIS security requirements)

Limitations of Current UX:

  • Dense data presentation without progressive disclosure
  • No guided onboarding for first-time users
  • Complex navigation between crime types, locations, and time periods
  • Assumes user familiarity with UCR terminology and data structures
