When I Google "Weight Map Analysis" the first hits are all this discussion. What's a weight map analysis?

Maybe it is better to say "Density Map".
Or sapatial population of something.
In this example from this address, they made a density cartography of bike stations...

So is there an underlying grid you want to use for sampling or should it be a smooth field? Also does it matter how much of a line is inside a grid cell, or do you just want to count the number of lines that intersect?

Thank you, but my version of GH is 0.9.76
I the boundy component is not working :(

15 co-planar lines of differing lengths, none touching.

Thank you for your reply,
But I mean the spatial density of the lines.
