To help you get started exploring these new viz types, we’ve asked Tableau Public Ambassador and Visionary Sarah Bartlett to share an overview of best practices for using Sankey and radial charts. From April 24th through June 30th, 2023, these new charts will be accessible through the “Marks” card drop-down menu on Tableau Public’s web authoring platform and will allow for the authoring and publishing of these charts natively to your Tableau Public profile. For a limited time, Tableau Public web authors will have the opportunity to test out two new chart types-Sankey and radial-with the New Chart Types Pilot. ![]() Reference Materials Toggle sub-navigationĮditor's note: We’re pleased to announce that for the first time on Tableau Public, we’re launching a special ‘pre-Beta’ pilot that invites the Community to have more influence on product direction.Teams and Organizations Toggle sub-navigation. ![]()
