United Nations maintains an interactive dashboard containing visualizations about world population and related parameters.
The things that I liked about the dashboard are:
- The back/return button at the top left corner of the map is very intuitive since they follow common application norms, such as undo/return on Microsoft applications.
- The icons used for fertility are super likable!
The things I did not like about this dashboard are as follows:
- The color mark used in the map tells which countries have higher and lower population without giving a numeric range to it. Worse yet, even when you hover on a country, there is no tooltip to mention the current population. Ideally, when you think about world population, we would want to know the growth rate for each country. This is probably the second most important data point (first being the current population) when you talk about the population domain. Both these data points are available in the additional parameter section to the user if he/she clicks on a country/region.
- There are four text filters at the bottom of the map, which partitions the world based on development index. When the user clicks on any one of these, the additional parameters get populated for the filter region selected. I would have liked the countries which fall under each of these indexes to be highlighted in the map when each of the filters were clicked. This would have helped the user to understand which countries are falling under them.
- When you click on a country, the map zooms in and its data points are presented in the additional parameter section. I don’t see the zoom feature fulfilling any purpose.
- The tooltips for “Maternal and newborn health” visualization is incorrect and there is no tooltip for “Sexual and reproductive health”.
