:joy: nvm what I just said, it seems like it also supports
``` years = [dA, dB, dc];
 populations = [pA, pB, pC];
Plot({ marks: [Plot.barY(populations, { x: years })```
this is always something I tried to get out from documentation but cannot find it anywhere

this is a perfectly fine data shape for Plot, just pass a {length} object as data, and your channels directly:
```Plot.barY({length: 3}, {x: [dA, dB, dc], y: [pA, pB, pC]})```

do you know where I could find these kinds of info from the documentation

<https://observablehq.com/plot/features/marks#marks-have-channels>

(search for “an array of values of the same length and order as the data”)

from this channel or google search or search bar in official doc?

to highlight the sentence in the page I linked to

oh thx a lot, I actually found it by myself

<@U048X1JDDHN> just an extra question regarding the matrix, it's quite general for table like data, but this is not supported by plot without custom transform right?
```[
  [d1, p1],
  [d2, p2],
  [d3, p3],
]```


you can use {x: "0", y: "1"} to read these values, and for some marks that is just the default, see <https://observablehq.com/plot/features/shorthand>

wow, really appreciate your help, it might take me forever to search them or until someone told me those exist
