Interactive Roadside Drug Test Dashboard

The Interactive Roadside Drug Test Dashboard is a web-based visual analytics platform that transforms Australian roadside drug testing data into interactive insights. It supports exploratory analysis through coordinated visualisations, geographic drill-down, demographic comparisons, and linked dashboard interactions for more effective data exploration.

Understanding roadside drug testing trends can be challenging due to fragmented datasets and static visual reports. Key issues include:

• Limited visibility into jurisdictional drug testing patterns
• Difficulty comparing demographic and regional trends
• Static charts that provide little interactive exploration
• Government datasets requiring extensive cleaning before analysis

The platform transforms publicly available roadside drug testing datasets into an interactive dashboard that supports exploratory analysis through coordinated visualisations. Major capabilities include:

• Jurisdictional Drug Test Analysis
• Geographic Drill-down Visualisation
• Demographic Trend Analysis
• Interactive Radar Chart Analysis
• Linked Dashboard Interactions
• Contextual Tooltips & Annotations
• Data Filtering & Cross-highlighting

• Data Visualisation Developer
• Designed and developed three interactive D3.js visualisations addressing key analytical questions
• Implemented geographic drill-down, linked dashboard interactions, and cross-filtering
• Developed radar chart interactions and comparative trend visualisations
• Built ETL workflows using KNIME for data cleaning, transformation, and aggregation
• Conducted usability evaluations and refined dashboard interactions based on user feedback
