Financial Visualization

• Definition
• Practice of making large financial datasets into

Methodology

• Symbol
• height of the tree represents trade volume
  (accumulated over a day)
• tree health (number of leaves) represents the
  trade price
• Setting
• assume the price change rate is within -10
  , 10
• Change tree once per minute

Data

• Our project
• 1. Extract necessary data from the source.
• 2. Calculate the average stock price and price
  change rate.
• 3. Map data into tree model

Image Morphing

• Purpose
• To achieve a smooth graphical transition from one
  tree to the next.
• Phenomena
• This process will last 1 second
• Old image fades out and new one fades in. (See
  example on the left)
