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

• We made two graphs that separate the information.
  • The first one shows the shipment routes and geographical information, that could be interesting, like if countries that reported waste generation are lying to each other, etc.
  • The second one shows the values of the hazardous waste production. That is acutally the key information in the graph and it's not necessary to show where these countries are.
• The values are ordered in a bar chart, which gives a better overview over the data.
• The ship routes are only labelled by the continents, the additional information (goods etc) is removed, because that information is not as important.
• The circles have been removed, because they didn't distribute as much information.
• Numbers have been put to an extra graph
• Removed the red color, because it was kind of an eye catcher
