The Skyline chart

This library provides a rising skyline chart, i.e. a skyline widget, which is linked to a dynamic history of buildings.

This chart has been created for the project Fitzhì. In Fitzhì, the goal is to display the history of a rising applications portfolio, confronted to the turn-over risk on these applications.

On the top right corner, two buttons, with one up and one down arrays, allow the end-user to zoom-in, or zoom-out the view.
