You need to analyze data for your business. What’s the best way to visualize it?

1 Know your audience

Before you start visualizing your data, you need to know who you are creating it for. Your audience will determine the type, style, and complexity of your visuals. For example, if you are creating a report for your team, you might use more technical terms and details, and focus on specific metrics and goals. If you are creating a presentation for your clients, you might use more simple and clear language, and focus on the big picture and the value proposition. Think about what your audience needs to know, what questions they might have, and how you can answer them with your visuals.

2 Choose your tool

When it comes to data visualization, there are many tools available with their own features, advantages, and limitations. Excel is widely used and easy to learn, but it has limited customization options and can be slow or unstable with large data sets. Tableau is powerful and user-friendly, but expensive and requires some training. Power BI is similar to Tableau but more integrated with Microsoft products, yet cheaper with fewer features. R is free and versatile, but has a steep learning curve. It's best to try different tools and compare their results or use a combination of tools to achieve different purposes based on your data, goals, and skills.

3 Follow best practices

Once you have chosen your tool, there are several best practices to keep in mind for creating effective and engaging visuals. Select the right type of visual for your data, such as bar charts to compare categories, line charts to show trends, pie charts to show proportions, and scatter plots to show relationships. Utilize colors, shapes, and sizes to highlight key points, contrast differences, or group categories. However, take care not to use too many colors or colors that are hard to see or distinguish. Labels, titles, legends, and annotations can explain your visuals and provide context. Make sure not to use too much text or text that is too small or too cluttered. You can also use filters, sliders, and buttons to allow your audience to interact with your visuals and explore different aspects of your data. Be mindful of not using too many or too complex interactions or interactions that are not intuitive or relevant. Finally, use layouts, grids, and white space to organize your visuals and create a logical flow. Avoid using too many or too large visuals or visuals that are not aligned or consistent.

4 Test and refine

Finally, before you share your visuals with your audience, it's important to test and refine them. You should check your data for accuracy, completeness, and validity, and make sure it is up to date, reliable, and relevant. Your visuals should also be checked for clarity, readability, and attractiveness. Additionally, your message should be checked for impact, relevance, and value. It's a good idea to ask for feedback from colleagues, peers, or experts; they can review your visuals and provide suggestions for improvement. Following these steps can help you create powerful and engaging data visualizations that can help you analyze data, communicate findings, and persuade an audience.
