index.html plot is weird and very tiny, most probably bugged

Hi there,
I managed to install your ActivityWatch plugin, and it works well to report data.
I think there is a bug in the `index.html` file though.
Here is what the plot looks like, after precisely following the instructions from https://github.com/Alwinator/aw-watcher-utilization?tab=readme-ov-file#custom-visualizations
It's all skewed on a specific time, and does not show a nice plot with different point like on your example.

Thanks in advance, if you have time to investigate this issue.
I'm available to test any change to the `index.html` or to answer any question you could have regarding this issue.
Regards, -- @Naereen.
