A system is provided that visualizes an allocation of resources. The system displays a chart, where the chart includes a list of tasks and a timeline including time units. The system further displays task indicators within the timeline of the chart, where a task indicator includes task indicator segments, and where an area of a task indicator segment is proportional to a work scope of a resource allocated to a corresponding task. The system further receives a user interaction that includes a movement of the task indicator segment from a first task indicator that corresponds to a first task to a second task indicator that corresponds to a second task. The system further allocates the resource from the first task to the second task. The system further modifies the display of at least one task indicator within the timeline of the chart based on the allocation of the resource.
