Data Visualization & Reporting Challenges
Data Visualization & Reporting challenges put you inside the work of turning numbers into decisions people can act on. You'll develop skills in Chart Selection, Chart Reading, and Dashboard Design, and you'll design KPI & OKR metrics while building KPI Dashboards that make performance legible at a glance.
From there you'll handle the harder edges — Storytelling with data, Multi-source data narratives, and Executive dashboards — working with Tableau or Power BI dashboards the way reporting teams actually do. Each challenge you solve earns a verified credential you can share with recruiters.
