viewof aggregatedPopulation $=\{$

const top $=$ vl$.$markBar$()$

$.$data$($population$)$

$.$encode$($

vl$.$x$().$fieldN$(\text{'}$Country Code'$),$

vl$.$y$().$fieldQ$(\text{'}$Population$,$ male $[$SP$.$POP.TOTL.MA$.$IN$]\text{'}),$

vl$.$color$().$fieldQ$(\text{'}$Population$,$ male $[$SP$.$POP.TOTL.MA$.$IN$]\text{'})$

$)$

$.$width$(1000)$

const bottom $=$ vl$.$markLine$()$

$.$encode$($

vl$.$y$().$sum$(\text{'}$Population$,$ female $[$SP$.$POP.TOTL.FE$.$IN$]\text{'}),$

vl$.$x$().$fieldN$(\text{'}$Country Code'$),$

vl$.$color$().$sum$(\text{'}$Population$,$ female $[$SP$.$POP.TOTL.FE$.$IN$]\text{'})$

$)$

$.$width$(1000)$

return vl$.$vconcat$($top$,$ bottom$)$

$.$data$($population$)$

$.$config$(\{$ concat: $\{$ spacing: $10\}\})$

$.$render$()$;
