This project explores the Electric Vehicle (EV) landscape in Washington State, with a special focus on Tesla's performance and market trends. Using publicly available vehicle registration data, the analysis evaluates Tesla’s market share, top-selling models, revenue estimations, vehicle performance comparisons, and adoption trends between Plug-in Hybrid (PHEV) and Battery Electric Vehicles (BEV). An interactive dashboard was developed using R and Flexdashboard to visualize insights and facilitate stakeholder-friendly reporting. The dashboard presents charts and graphs that provide clarity on Tesla’s dominance, model-wise sales, average range, and pricing compared to other EV brands.
