The Data Visualization components in ADF allow for turning data into information using a large variety of representations. The DVT library ranges from bar, pie and line chart to map, gantt and gauge. With others in between. On our ADF Special Interest Group at AMIS, we discussed six components from the DVT collection. This presentation is one out of those six - on Gantt Charts.
