+# Dependency visualization for code review
+
+Could visualizing changes improve your patchset quality and review time?
+
+Softagram's automated Impact Report presents patchsets' new, removed, and
+changed files and dependencies in an easy-to-understand graphical format,
+along with insights into hidden dependencies (co-changed files based on
+git history) and architectural violations.
+
+In this short showcase, we will present our new approach, and discuss how
+visuals and transparency would improve architectural quality and make code
+reviewers' lives easier.

+### Michael Watkins - Softagram {#mwatkins}
+
+Michael joined Softagram as a backend developer in the beginning of 2019,
+helping to reinforce the small team of developers in their new approach to
+code review and source code visualization. Shortly after joining the company,
+he began working on integrating Softagram's impact reports into the Gerrit
+workflow. Although he had no prior experience with Gerrit, Michael quickly
+learned some of the ins and outs, and is on his way to becoming a Gerrit
+expert. Besides sharing Softagram's simplified approach to code review at
+the Gerrit User Summit in Sweden, Michael is looking forward to participating
+as an attendee and continuing to build on his Gerrit Code Review knowledge.
