This interactive Flexdashboard explores Australia’s National Electricity Market (NEM) energy generation mix for the last seven days using data from OpenNEM and AEMO. It visualises renewable and fossil fuel generation trends, source contributions, and hourly performance through interactive Plotly charts. The project demonstrates advanced R-based data visualisation and storytelling using ggplot2, plotly, and flexdashboard for MATH2237/MATH2270 at RMIT University.
