Visual graphic shows how the value and composition of the index has changed over 26 years

Jeremy Christopher developed this information visualisation to explain the history, worth and importance of the FTSE 100.

The work shows the base rate (first value of the index) and the value over its 26 year history. It also shows how the numbers of businesses from different industry sectors has changed over time.
