[Bug]: Cannot draw multiple lines with empty point

[stregouet]

Bug description

hi,
first thanks for this great project! This is a long time I try to build a chart declarative library for solidjs and you dit it!
Here is my bug: I try to build two lines on a graph but there are some hole in the second line (there is no y data for some x), but console report some errors when I try to plot these points: I get some NaN in line and path svg. Do you see any workaround?

Reproduction Link

https://github.com/stregouet/test-solidcharts

Reproduction Steps

my reproduction repo is just a npm create vite@latest with a FirstChart.tsx component. If you run npm run dev and go to localhost:5173 you will see error in browser console because of the following lines

  if (index === 3) {
    delete data.value2;
  }

Expected behavior

I expect a way to configure second line on how to handle missing point or just ignore missing point.
