Removing unnecessary elements when communicating with charts can greatly impact the effect the chart has on your audience. If a chart appears complex, we assume it is hard to read. A cleaner chart is more likely to be read by people. When the chart focusses on a message, it is easier for your audience to focus directly on what is important.
To understand the benefit, let’s look at an example. Consider how would you declutter this chart.
Here is the progression I went through to declutter this chart.
Each step is a small one, but collectively they make a huge impact on the final chart.
Here are some components you can consider removing or editing to declutter your chart.
