The visualization made it possible to point out some problems in the project, such as long bug lead times. However, the data was just a flat export of bugs from Jira. The data did not contain any time based event data (issue state changes, assignments) and it did not take into account Jira comments. Thus a richer data source was needed, which would have more detailed data of the Jira events. Therefore, the visualization should illustrate more Jira’s metadata information. Thus, we decided to drop the idea of visualizing any of the version control data and focus on data mined from Jira.
