Slide 1: The Challenge of Financial Data

Static financial reports are often:

  • Difficult to navigate: Users cannot zoom into specific dates.
  • Lacking Detail: No tooltips for exact closing prices.
  • Static: One view fits all, with no ability to filter indices.

Our EU Stock Explorer solves these issues by providing a dynamic, web-based interface for historical market analysis.

Slide 2: Data Integrity & Live Processing

The application is powered by the EuStockMarkets dataset. It tracks the daily closing prices of four major European indices (1991–1998).

Live R Execution: Below is the summary of the DAX index, generated directly by R code during the slide render:
