An example of a chart containing gratuitous chartjunk.This chart uses a large area and much "ink" (many symbols and lines) to show only five hard-to-read numbers, 1, 2, 4, 8, and 16.
Without any sense values have a precision up to 16 decimal fractions, which means 10-16 pixels. Cleaned with SVGomg the file will be less than half the size.A good method to generate bar charts seems the Template:{{Bar chart}}.The best method to generate bar charts is the Template:{{Graph:Chart}}.

@media all and (max-width:720px){body.skin-minerva .mw-parser-output div.mw-graph{min-width:auto!important;max-width:100%;overflow-x:auto;overflow-y:visible}}.mw-parser-output .mw-graph-img{width:inherit;height:inherit}
