We’ll take an afternoon to discuss tips for making effective plots and learn about new visualization technologies, including webapp servers for interactive plots and manipulations of astronomical images. Data sets will be provided, such as the TESS Object of Interest catalog, TESS Full Frame Images, and TESS engineering data. Includes a 30 minute introduction and pitch session, 1 hour for hacking/coding, and 30 minutes to present results/progress. The hacking group can stay after the presentations if there is sufficient interest. Bring your laptop!
