Question 8202
What one would want to show is "How many households have how many children?"
You group all the answers that have no childred together and count them. I see 4 households that have no children. So, for no children, the count is 4. A line chart of this would have a line labeled 0 (for number of children) and would be 4 long.
The same is done for each of the other numbers of children. I see 6 households that have 1 child, 6 households that have 2 children, etc. 

A start would be to draw lines for those three numbers of children:

Number of children |
0..................|XXXX
1...................|XXXXXX
2..................|XXXXXX

etc.
I have shown this as a horizontal chart because it is easier to type here, but you could turn the chart 90 degrees to the left and get a vertical chart.
