A Bad Visualization: The J Curve
Source: The J Curve: A New Way to Understand Why Nations Rise and Fall
Author: Ian Bremmer
I think this is a bad visualization because the graph is very un-informative. It has two dimensions: stability and openness, and the arrow, which signifies the tendency of change.
Way of improvement:
1. add points on this graph to signify the position of different countries with respect to these two measures.
2. add colors on this graph to show author's opinion on good and bad side of the graph.
x-axis is the "openness" of a country from low to high (left to right; y-axis is the "stability" of a country from low to high (left to right).
A Good Visualization: The Victorian Years

I think this is a good visualization because the graph is very informative, and represent the information in just the right density -- not too cluttered.
It shows the following dimensions:
1. the 3D visualization of the exterior of the house
2. the cut-across visualization of the internals of the house
3. illustrations of different parts of the house
4. reference to other part of the book for relevant information
5. zoom-in view on the object
6. zoom-out view on the surrounding public facilities
7. map of the region
8. hitory time-line of the corresponding period
I think this is awesome example of good visualization of information can help people to understand and learn much faster than poor or no visualization!!
The timeline on the bottom show some famous social events in the period of 1850 -- 1900 (The Victorian Years).
The house above show a three dimensional picture visualization of a victorian style house with cut-across view of the internal settings.
On the top is a map showing the extent of the city comparing now in yellow and then in 1870. The map has color showing different historic times and area showing the city boundries.
