Plotly Studio known issues

Last Updated: November 12, 2025

Plotly Studio Hangs at Startup

Plotly Studio may hang on the initialization screen when launching the application. This issue has been observed on both Mac and Windows operating systems.

Known Workarounds:

• Attempt to restart Plotly Studio to determine if the issue persists.
• For macOS users, please ensure you have installed Plotly Studio into your Applications directory. It cannot run from within the .dmg.
• Ensure that you have ample disk space to run Plotly Studio.
• If you are a Windows user, please ensure you have installed the C++ Redistributable. You can find the latest supported version at: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170
• If you are using Plotly Studio in an enterprise network setting, you may need to have your IT department grant explicit access to use Plotly Studio. You may also need to allow connections to download dependencies from PyPI and Github.

Cannot Update Application Data

If you need to update an app's CSV file, there is a prompt workaround you can use to do this: 

Load data from ~/Data/my_dynamic.csv and write it to the local project directory if it’s available. Always use the latest data file in the project.

This should copy the new data file into your project and your app should now be using the latest data file. If you choose to deploy this app, it will deploy with the latest data file at the time of deployment.

Note: We are actively working on a new Data Sources and Data Views feature that will replace this static data workflow. Stay tuned for updates!

Layout Editing Has No Preview

When attempting to edit the layout of your application, you won't see a preview of the layout, this is intentional. To make changes to your layout, update the Layout prompt (e.g. reordering the chart list, or updating their width to a different percentage). Press Submit. Once finished, your app preview should update with the new layout changes.

 

Failed to Generate App Outline

Users may encounter an error message stating, "An error occurred while generating the outline. Please try again." This issue typically arises when Plotly Studio misinterprets the provided data, often due to specific data characteristics.

Workarounds:

• Clean Header Rows: Ensure that your header rows are machine-friendly. Plotly Studio will struggle with column titles that are structured like sentences, or have embedded punctuation (leading spaces, tabs, periods, comas, semicolons, etc). For the best results, use plain column headers where spaces are replaced with underscores, e.g. annual_sales.
• Ensure data has relatively few sparse rows: Plotly Studio may struggle to generate an accurate app outline if the input data contains a significant number of rows with missing or null values across many columns. Consider cleaning your data to reduce sparsity before attempting to generate the outline.
• Cell values include escaped commas and/or special characters: Escaped commas and special characters within your data can sometimes lead to misinterpretation by Plotly Studio's parsing mechanisms, causing the outline generation to fail. Inspect your data for such instances and remove or reformat these columns as needed.

 

 

Can't Install Libraries from PyPI

Plotly Studio currently does not allow the user to install custom dependencies from PyPI. This can prevent certain analytical operations or visualizations from being performed.

Workarounds: None. We are actively developing a dependency management user interface (UI) that will launch after GA in September, enabling users to manage and install required packages.
