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
