Software visualization is the visual representation of information gathered from soft-ware applications about their architecture, design, behavior and evolution. In our case, software visualization is a powerful tool to represent evolving software stocked in a ver-sioning repository by using current software metrics. Since versioning repositories can always be queried to obtain a working copy for a given revision and since revisions are directly tied to time, working copies can be considered snapshots taken on the history of a project or software. It is therefore natural to apply metrics computation on soft-ware entities existing in a given working copy to construct a history of evolving metrics values. Moreover we believe that aggregating different types of metric measurements performed at multiple level, from revisioning activity itself to design metrics, will sup-port and enhance sofwtare evolution analysis to easily find out past causes of current problems and to forecast possible issues in the future life of a software application
