| "The Changing Nature of Middle-Class Jobs annotated" |
As one piece this graph does a poor job of explaining the data that it references. This chart gives a rough idea of how job trends have changed for certain fields over time. The graph has two different colors that signify male and female.
This graphic does not correctly show data at first glance. It's hard to make out the scale that the system is using. Also, it's not clear on the bottom of the +/- on the data. I find that the graph's scale could be more scaled. This is pointed out where its a major gap in the data, and one goes higher than the other. I also find it hard to ask a simple question, such as "What major changes were observed from 1980 till 2012".
Below are some things that could make this graph be more clear:
- In annotation "A", it shows the number of job changes as a single number, while the scale goes by 1000, so for example 20 means 20,000. Also since each section has multiple lines, it's unclear now which profession has got an increase in jobs.
- Annotation "B" shows both a -/+ under the job info, I find this confusing as the graph goes up and down in each category. I wish they had used a more clear indication that the graph was going up or down in that section.
- Lastly, annotation "C" uses a scale to indicate "red" being female(s) and "blue" is for male(s). The part in the middle of the legend is not clear if it is showing the split between female and male. I wish that this was more clear, so if someone was looking at this graph, they would find it hard to figure.
Overall, I think the visualization looks really nice and organized in a nice to read format. Since the graph uses different colors to distringuish the differences it makes the graph more clear to read at a glance, it also gathers your attention more quickly. This graph is interactive, which I something that I enjoy, as you can hover your mouse cursor over each line to see what job that line refers to. Lastly, I feel that this graph gives you a good overview of the major job sectors and each of the jobs that fall in that section. I think the visual is very good but it does need some improvements made to make it easier to read.
