Critique about the Graph

• data ink ratio is very high
• The world map is not really necessary (except for showing the shipment routes)
• The circles are overlapping
• The values are not ordered (because they are shown on the map)
• The label "Total Hazardous Waste Production" can't be attached to anything in the first moment
• Much unimportant information, only the necessary info should be on the graph:
  • The circles as descriptors include the information about the ratio between country size and hazardous waste production.
  • Sublabels of Arrows: what's shipped?
  • Major Illegal Waste Shipment Routes" don't really fit into the question "Which countries produce the most hazardous waste?"

Redesign

Total hazardous waste production in metric tons

Explanations

• The essential information is the waste production (according to the graph's title). So we removed all the other information.
• The diagram now only has the necessary information
• Data ink ratio is very low (no 3D effects, no additional lines/axis that don't show any information etc.)
• The values are ordered in a bar chart, which gives a better overview over the data.
• Removed the red color, because it was kind of an eye catcher
