Last week, the Plotly chart component suddenly stopped formatting text as Arial and now presents everything in what I assume is Times. We've seen the issue across all operating systems and browsers, and across multiple components (including newly added).
Hi @jericsinger,
Thanks for reaching out! I don't believe we've changed anything with the functionality of the chart component 
Could you share an app export? Or screenshots of one of the chart's configuration?
Do you have any custom css in the app or in your Retool org?
Lastly, could you try testing the app in an incognito window?
