Hi all, I have a super easy question for you. Why does this script fail with
"ValueError: expected an element of Dict(String, Seq(Any)), got {'w': 4}" ?
from bokeh.models import ColumnDataSource
d = {'x' : 1, 'y' : 2, 'h' : 3, 'w' : 4 }
ds = ColumnDataSource(d)
That is basically the same as the ColumnDataSource usage here, and in
various other examples.

So I am kind of confused- thanks in advance.

ColumnDataSource expects an argument of a dictionary of sequences. You have a dictionary of ints. To get it working, you can write something like this…
d = {‘x’ : [1], ‘y’ : [2], ‘h’ : [3], ‘w’ : [4] }
It should work if the values are set as list:
‘W’: [4]

Thanks James, and Daniel. I was hung up looking at the
tests/glyphs/Rect.py and not paying enough attention to the error
