'Chart Junk'

Here's something tweeted from FT's Alphaville.  https://ftalphaville.ft.com/

It was created by Standard Chartered Bank.  It's a bar chart, where the top or bottom of each rectangle represents a value.  It's fine, but as is often in graphics, 'less is more.'  There's a lot of ink for each data point, where a simple line, perhaps with points to highlight that these are discrete observations, would have done the job.  One of my teachers called such unnecessary ink 'chart junk.' 

I like bar charts better when the bars actually mean something such as components of the overall number you are tracking.  Bloomberg did this with the chart in my prior blog post https://betterdatavisualization.blogspot.com/2018/10/bloomberg-bar-charts-shows-more-is-less.html.  Unfortunately, they did some other things to that ruined it.
