IRV - Divide the 'mapInfo' into sections and show bar charts

[ptormene]

When a zone is clicked on the map, we want to display information in a more readable and structured way, dividing variables by section (e.g. keeping in a same section all the primary indicators) and displaying bar charts instead of numbers.
