In order to show financial information in a comprehensive and attractive manner we have decided to use the D3 (Data Driven Documents) library that is the data visualization standard for web applications. In order to simplify the interaction of the user with the web application, it was decided to manage the 3 portfolio parameters (Risk, ROI, Lifecycle) using simple sliders. Modifying the value of each parameter, the user obtains new optimized values of the two other parameters and a new portfolio structure in form of a pie chart.
