Describe the bug

When trying to plot the example proposed in: https://github.com/Kotlin/kandy/blob/main/examples/idea-examples/lets-plot-simple/src/main/kotlin/org/jetbrains/kotlinx/kandy/letsplot/simple_lets_plot.kt

I got the following exception:

Hi, we couldn't reproduce this bug. Could you please specify the Kotlin version and your OS? Lets-plot uses the Batik library to save plots to PNG, which is platform dependent. You can also try to use an actual dev version (0.4.5-dev-31).

devcrocod commented 1 month ago

This bug doesn't reproduce on the latest versions of the library (since 0.5)
