Calling all data designers: Join more than 1,600 fellow data visualization enthusiasts in honing skills and sharing ideas with Makeover Monday. The project offers a free "learning and development appointment with yourself." The site provides prompts and data sets to challenge users' data visualization mastery. Before diving in, it may be helpful to explore the "6 steps to your first #MakeoverMonday viz" graphic, found on the home page. As these steps explain, Makeover Monday releases a new data challenge each week. Visitors can view these weekly challenges (as well as archived challenges from 2016-present) under the Data Sets page (found in the Participate menu). Provided with a topic and a data source, users are encouraged to create a project and share it with the rest of the community. Designers can share their work via the Submit page (also under Participate) and on social media channels using #MakeoverMonday. To view other community members' submissions, check out the Makeover Monday website's Blog (found in the Learn menu) or Gallery (found in the Participate menu). For additional learning opportunities, readers should consider joining a weekly webinar. Check out the Webinars tab (under Learn) to view past and upcoming topics and create a free account for registration purposes. Makeover Monday is made possible by partnerships with The Information Lab, Exasol, I for Ideas, BrightTALK, and data.world.
