Too much variety

[sumaiyakhatun27]

Dashboards often include multiple types of visualizations to avoid monotony. For example, you might compare this year's sales to last year's sales for several products. A line chart would be ideal here, but the designer might want to use bars, columns, or something else to avoid the dashboard being just lines.

The key is to use elements that are different from all existing visualization methods, kazakhstan mobile database such as colors and headings, to attract the user's attention.
Lots of embellishments
The most common (and easily correctable) mistake is using elements that add nothing to the metrics, serving only a purely decorative purpose.

3D graphics and thematic images can distract rather than help users. Visual content that is not supported by data is best left out of the dashboard and reserved for infographics.
Misleading similarity
Carelessly using the same design ideas across a dashboard can result in all elements "merging" together. Users are forced to spend time focusing on the data they need before analyzing it.

Don't hesitate to use the same visualization (or element) twice for similar descriptions or needs.
