HTML Preview installs statistics

HTML Preview in VSCode

Simple preview for HTML (.html) or Scalable Vector Graphics (.svg) files in VSCode. The main use case for data science is to preview interactive statistical graphics created using Plotly in Python notebooks and exported to (.html) or (.svg) files.

The Plotly HTML graphics files are not static images, but preserve interactive features and allow users to make their own explorations of the data. The extension allows you to preview the graphics files directly inside VSCode, which means you don't loose focus by leaving the environment to open the graphics in a browser, and allows you to organise your graphics along with your notebooks inside the VSCode editor.

HTML Preview of interactive map of global seismicity, volcanism, and plate boundaries created using Plotly.
