Data Summaries to Make Datasets Actionable

Data Visualization Challenges

I once had trouble understanding survey data from a customer feedback report for a product launch. The dataset had responses from hundreds of customers, and it covered numerous aspects of the launch’s feedback, such as satisfaction levels, product usability, feature preferences, and so on. The data was presented without much care for visual appeal: it was cluttered, the spreadsheet had rows of numbers representing ratings on a scale of 1 to 10, along with free-text responses. It was just a lot of raw data made that could have been simplified and categorized better.

The big issue was the lack of visual representations. A set of bar charts or pie charts could have been used to visually show satisfaction levels across different product features; that would have made the data more fit for human consumption. With a visual representation of these ratings, we could have seen more simply which features customers liked or didn’t like. This would also have helped with seeing patterns across different customer demographics, like age groups or regions.

Another way to improve clarity would have been by grouping similar responses and showing areas of high satisfaction and dissatisfaction. For example, if several features had low usability scores, a heatmap could have been used to bring attention to these problem areas.
