1. Best practices
Welcome to our final lesson. We'll look into some data visualization best practices that will help you refine your data storytelling product.2. Simplicity and clarity
Creating a clear and simple visualization can greatly enhance the effectiveness of your message. To achieve this, we need to reduce complexity by focusing on the most important aspects of our data. It's also important to use clear language and minimize non-data ink (the elements that don't communicate data). Take a look at this example. I'm sure you have encountered charts like these before. Are all of the elements in this chart necessary? Could you make it simpler?3. Labeling axes and providing a clear title
In order for our audience to understand our visualization, we need to label the axes and provide a clear title. This helps to communicate what the data is and what message we are trying to convey. We also want to use descriptive axis labels that explain what the data represents. Additionally, you can also employ descriptive subtitles to explain the point of the chart, as well as captions to document the data sources. Take a look at this example and see how labels are being employed. Which one do you think is the clearer plot?4. Be consistent
Consistency is key when it comes to creating effective visualizations. Make sure to use consistent formatting throughout your visualizations, including font size and style, chart types, and color schemes. Using a consistent color scheme can also help viewers to easily identify different elements of your visualization. Additionally, try to use the same type of chart for similar types of data, as this can make it easier for viewers to compare between them. Think about the plots that have been used as examples throughout this course. They have all used the same font and colors to respect Datacamp's brand. If I had used a plot like this, it would have looked out of place, wouldn't it?5. Accessibility matters
Accessibility is also a crucial consideration when creating data visualizations. Not everyone experiences visual content in the same way, and it's important to ensure that your visualizations are accessible to all. One way to make your visualizations more accessible is to provide alt text for images and graphs, which allows screen readers to describe them to those who may not be able to see them. Another important consideration is colorblindness. It's important to take this into account when choosing colors for your visualizations and to avoid using color schemes that may be difficult to differentiate for those with color vision deficiencies.6.
