Hmm, could you perhaps provide a rough example of what the chart would look like with the data you've provided?
Something like this (see below), pretty basic. I'd like to have the different fields I've posted in the first post in the x-axis (Lie T(M) NEW; Energia T(M) NEW; etc.) and the values (45, 62, 51, etc.) in the y-axis.

Ah...yeah, I don't think the extension's built to display data in a single row like that easily, and so you probably need to transpose the data I'm afraid
Probably someone with more VegaLite experience than me will be able to come up with a solution that lets you display the chart like that while keeping your data intact
