Understanding and Overcoming the 404 Error When Embedding Plotly Charts in Jupyter Notebooks with HTMLWidgets

Understanding Jupyter R Plotly 404 Error

Introduction

The popular data science and visualization platform, Plotly, can be used to create interactive and dynamic visualizations in Jupyter notebooks. However, some users have reported a common issue when trying to embed Plotly charts into HTML files within Jupyter notebooks: the “404 Not Found” error.

Causes of 404 Error

In this section, we will explore the possible causes of the 404 error when trying to embed Plotly charts in Jupyter notebooks.

Incorrect File Path

One common cause of the 404 error is an incorrect file path. The embed_notebook function generates a URL that points to a non-existent file. This can happen if the file name or directory path is not correct.

Solution: Using HTMLWidgets to Save and Embed Plotly Charts

In this section, we will discuss a solution to embed Plotly charts in Jupyter notebooks using the htmlwidgets package.

To save the Plotly chart as an HTML widget, you can use the following code:

library(plotly)
library(htmlwidgets)

p <- plot_ly(ds, x = x, y = y, mode = "markers", group = group, size = size)

# Save Plotly chart as an HTML widget
widget <- htmlwidgets::saveWidget(as.widget(p), "index.html")

This code saves the Plotly chart as an HTML file named index.html.

Embedding Plotly Chart into Jupyter Notebook using rawHTML

To embed the Plotly chart in the Jupyter notebook, you can use the following code:

library(htmlwidgets)

# Read HTML content from saved widget
rawHTML <- paste(readLines("index.html"), collapse = "\n")

# Display embedded plotly chart using display_html function
display_html(rawHTML)

This code reads the HTML content from the saved widget and displays it in the Jupyter notebook using the display_html function.

Workaround for MacOS Users

Some users have reported issues with the above solution on MacOS. To work around this issue, you can use a different approach:

library(plotly)
library(htmlwidgets)

p <- plot_ly(ds, x = x, y = y, mode = "markers", group = group, size = size)

# Save Plotly chart as an HTML widget
widget <- htmlwidgets::saveWidget(as.widget(p), "index.html")

# Use rawHTML function to display embedded plotly chart
rawHTML <- paste(readLines("index.html"), collapse = "\n")
display_html(rawHTML)

This code uses the rawHTML function to display the Plotly chart in the Jupyter notebook.

Conclusion

In this guide, we have discussed a common issue when trying to embed Plotly charts into HTML files within Jupyter notebooks: the “404 Not Found” error. We have also provided solutions using the htmlwidgets package to save and embed Plotly charts in Jupyter notebooks. By following these steps, you can successfully display your Plotly charts in Jupyter notebooks.
