1. Design Principles in data visualization with real-world examples.

2. Data visualization is the graphical representation of information and data. It's a way to communicate insights, patterns, and trends in data through visual elements such as charts, graphs, and maps. In today's data-driven world, data visualization plays a crucial role in helping us understand complex datasets and make informed decisions. What is Data Visualization

3. Design principles in data visualization ensure clarity, simplicity, and effectiveness in conveying information. They guide the creation of visualizations that are easy to understand, engaging, and accurately represent data. Without these principles, visualizations risk being confusing, misleading, or overwhelming to audiences, hindering their ability to derive insights and make informed decisions from the data. Why do we need design principles

4. Bar Charts When you start your axis above zero, you shrink the bars and skew the way your data looks, often confusing the viewer and robbing them of context. You also want to avoid gaps in between your bars that are uneven or too large. This can be a result of poor design or an axis that isn’t scaled evenly.

5. Line Charts Be very selective with the text you choose to add to your chart. Label the axes if the information provided needs further explanation. Add a pop of color or a few words of text to focus your viewer’s attention

6. Pie Charts The human brain is very good at distinguishing differences in length and volume, which is why bar and column charts are so popular. What the brain isn’t good at, though, is comparing angles. Never ask your viewer to compare one pie chart with another pie chart. This practice is confusing and time-consuming.

7. Maps Nothing is worse than a cluttered, hard-to-read map. Don’t make your design so elaborate that people can’t understand your message quickly. Resist the urge to add all of the information you have in the form of legends, text, labels, and images. That being said, you don’t want to leave out crucial information that your viewer needs for context and deeper understanding.

8. Pictorial Charts The right icon is key to the perfect pictorial chart. Don’t pick a generic icon that doesn’t relate directly to your story. You want to grab people’s attention and understanding quickly, not leave them wondering what they’re looking at. You also need to think about where people will be viewing your chart. If it’s relatively small, say on a mobile device or a sheet of paper, you don’t want to pick an icon with a lot of detail that’s tough to see.
