Visualization of software applications plays an important part in the process of comprehending new software systems and is even more important due to its increasing complexity. Component-based development works with complex structure of black-box units and paradoxically there is not much choice in terms of both notation and tooling when one needs to visualize structure of these component-based applications. Reverse engineering is available for only a few component models and the state of the practice in visualization is the simple and static component diagram introduced in UML 2.0. In this paper we present a tool that is generic and it is therefore usable for any component-based application. This tool works with an advanced meta-model (ENT) as an intermediate data model to store all the reverse-engineered information about these applications. This information is then available for further visualization. A new notation based on this meta-model is also suggested in this paper which uses several interactive techniques to enhance the comprehension process.
