Data Visualization

Data visualization is an important--and overlooked!--tool in the software engineer's tool belt. Bryan describes a recent journey with gnuplot while Oxide colleague, Charlie Park, shares his own experience with data visualization and Adam offers a visual analysis of Simpsons episodes. Stay tuned to the end to find out about the Oxide and Friends book club coming up in May.
In addition to Bryan Cantrill (mastodon.social/@bcantrill) and Adam Leventhal (mastodon.social/@ahl), we were joined by Oxide Colleague, Charlie Park.
