Example to ilustrate this question at gis.stackoverflow.
We choose to replace Turf with JSTS.
If the result is more complex (i.e. the resulting intersection is a polyline), the algorithm should be repeated for each part in the polygon.

Using JSTS to measure how far a line travels through a polygon
View README.md
This simple line chart is constructed from a TSV file storing the closing value of AAPL stock over the last few years. The chart employs conventional margins and a number of D3 features:
This also uses simple-statistics to derive a linear regression of the price changes.
- d3.tsv - load and parse data
- d3.time.format - parse dates
- d3.time.scale - x-position encoding
- d3.scale.linear - y-position encoding
- d3.extent - compute domains
- d3.svg.axis - display axes

vega for time series chart with shaded blocks
View Readme.md
vega stocks spec forked to add shaded blocks
Often time series charts can be enhanced by shaded blocks to highlight events or periods as shown by this example which uses the R package xtsExtra. Vega specs already allow this functionality, and it is fairly easy to implement.
I added an events object to the JSON data array.
