Here are the Power BI visuals and features I used:
- New Card Visuals – for a clean, impactful display of candidate details and key metrics.
- SVG - Bar chart showing the candidate's electoral votes potential wins
- Line and Clustered Column Chart with Error Bars – to represent time-series polling data with uncertainty ranges.
- Dynamic Weighted Moving Average – the biggest challenge! I set up a complex line chart using a weighted moving average with a dynamic parameter to control the period (1, 2, 3, or 4 weeks), allowing flexible trend analysis.
Power BI has immense potential to ease data journalism by enabling journalists to quickly and effectively create insightful, interactive visuals quickly and effectively. This tracker is designed as an educational tool to showcase Power BI's potential for data storytelling.
