World Olympics Animated Tableau Dashboard

Built an animated, interactive Tableau dashboard to explore Olympic results alongside country GDP over time. The project involved extensive data wrangling, integration, and cleaning before visualization.



Key details

  • Cleaned and integrated 270k+ rows and ~80 columns of Olympics and GDP data using Microsoft PowerQuery and Excel.
  • Produced 7 interactive chart types and 5 selectors to let users explore medal counts, trends, and GDP relationships.
  • Public Tableau dashboard

Notes

  • Consider embedding a static thumbnail or an iframe preview on the portfolio page if you want the dashboard to be visible directly on the site.
