One of the simple tasks:
Web application must read any CSV/TXT file with: N,FROM,TO, Description, Color ...........minimal initial table structure
and draw a rectangular "chart" like ONE column histogram representing a stack of different blocks in different colors (and hash patterns) with editable height and editable description (table records details). A table of source records must be presented in a grid, + some minimal required user interface objects.
Nothing fancy - just basic CRUD functionality.
It is for estimation of the workload and efficiency and move forward.
