What’s the secret for D3’s long-time success?  Mike Bostock, the creator of D3 shares the reasons for his data visualization tool’s longevity, and why it won the 10-year Test-of-Time award from the IEEE. Mike goes deep on D3 and Observable, which he also founded, and talks about all things visualization with The Data Wranglers Joe Hellerstein and Jeffrey Heer, including when it’s OK to use a bar-chart for getting quick data insights and the applications of time zone wrangling.  #TheDataWranglers
