Description
Bug description
When rendering to a PDF, code that flows off the page is lost:

It would be nice if quarto would be able to use some kind of line wrap for the code when rendering to PDF.

title: Analysis

Now that we have the data in a tidy format, let's clean the values:
1. Convert all `"-"` to `"0"`
2. Convert all `"x"` to `"0"`
3. Convert all the values in the `:Value` column to a Float64 and a `:Year` column to an Int
```{julia}
df = transform(df, :Value => ByRow(x -> ifelse(x == "-", "0", x)) => :Value)
df = transform(df, :Value => ByRow(x -> ifelse(x == "x", "0", x)) => :Value)
df = transform(df, :Value => ByRow(x -> parse(Float64, x)) => :Value, :Year => ByRow(x -> parse(Int, x)) => :Year)
first(df, 3) #| hide_line
```
When I run quarto render --to pdf I get a PDF like in the screenshot above.
