What is the main goal of the 'Charts Systematic Construction' step?

• To randomly select colors for the chart

• To create charts based on visualizer's requirements

• To generate a list of possible data subsets

• To evaluate the salience map

What is the effect of texture on salience in the revised color palettes?

• It decreases salience

• It has no effect

• It increases salience

• It makes salience more precise

What is the impact of using a palette with a predominant color?

• It weakens the salience

• It strengthens the salience

• It has no impact

• It makes the salience less precise

What is the effect of using the 'strongest' color in some data?

• It weakens the salience

• It improves accuracy

• It has no effect

• It makes the salience less precise
