hello. I am in the process of creating an hbar. I tried to use tooltips so that the y value and the right value of the hbar come out when I hover over the graph, but as shown in the picture, type:??? value:??? is displayed, so I tried using hover, but it’s the same. If so, what should I do? The bokeh version is 3.1.0. Any help would be greatly appreciated.
Thank you for help me.

show(p)
This is my csv file data when I run print(row)
[‘출생아수’, ‘436500’]
[‘사망자수’, ‘266257’]
[‘생산가능인구(15-64)’, ‘370140’]
