Correct: Design thinking is a process used to solve complex problems in a user-centric way. It enables data analysts to identify alternative strategies for visualizations.
4. While creating a data visualization for your stakeholders, you realize certain colors might make it more difficult for your audience to understand the data. So, you choose colors that are more accessible. What phase of the design process does this represent?
- Define
- Prototype
- Empathize (Correct)
- Test
Correct: Considering appropriate colors for a visualization is part of the empathize design phase. During the empathize phase, you consider the emotions and needs of the target audience for your data visualization.
hands-on activity: making your own visualization

- The design thinking process (Correct)
- The brand of visualization software you use
- The needs of your audience (Correct)
- The type of data you are visualizing (Correct)
Correct: In order to make an effective visualization, you must consider the type of data you’re visualizing, the needs of your audience, and the design thinking process. An effective visualization can be made in any visualization software. Going forward, you can use your knowledge of creating data visualizations in the chart editor to explore more types of data visualizations. This will help you better present your data and findings to peers and stakeholders.
Test you knowledge on exploring data visualization
1. What are the three basic visualization considerations? Select all that apply.
- Labels (Correct)
- Subtitles (Correct)
- Text
- Headlines (Correct)
Correct: The three basic visualization considerations are headlines, subtitles, and labels.
2. Directly labeling a data visualization helps viewers identify data more efficiently. Legends are often less effective because they are positioned away from the data.
- True (Correct)
- False
Correct: Directly labeling a data visualization helps viewers identify data quickly. Legends are often less effective because they are positioned away from the data.
3. Why do data analysts use alternative text to make their data visualizations more accessible?
- To make data visualizations easier to read
- To add context to the data visualization
- To make the presentation of data clearer
- To provide a textual alternative to non-text content (Correct)
Correct: Alternative text provides a textual alternative to non-text context. Alternative text ensures that users who need to access your data visualizations in different ways, like with a screen-reader, will still absorb the information.
4. You are creating a data visualization and want to ensure it is accessible. What strategies do you use to simplify the visual? Select all that apply.
- Focus on necessary information over long chunks of text (Correct)
- Simplify your visualization (Correct)
- Do not include labels
- Avoid overly complicated charts (Correct)
Correct: Simplifying your data visualizations can help your audience understand and focus on the important data. To do this, avoid overly complicated visuals or unnecessary information.

Share Data Through the Art of Visualization Weekly Challenge 1
1. A data analyst working for an e-commerce website creates the following data visualization to show the amount of time users spend on the site:
What type of visualization is it?
- Correlation chart
- Line graph
- Scatter plot
- Histogram (Correct)
Correct: It is a histogram. Histograms demonstrate how often data values fall into certain ranges.
2. What do correlation charts reveal about the data they contain?
- Relationships (Correct)
- Changes
- Visualization
- Causation
Correct: Correlation charts indicate relationships among data.
3. You are creating a presentation for stakeholders and are choosing whether to include static or dynamic visualizations. Describe the difference between static and dynamic visualizations.
- Static visualizations separate out the individual elements of a single visualization. Dynamic visualizations combine multiple visualizations into a whole.
- Static visualizations combine multiple visualizations into a whole. Dynamic visualizations separate out the individual elements of a single visualization.
- Static visualizations are interactive and can automatically change over time. Dynamic visualizations do not change over time unless they’re edited.
- Static visualizations do not change over time unless they’re edited. Dynamic visualizations are interactive and can automatically change over time. (Correct)
