How-To: Graphing COVID Time Series Data Using Chart.js and Postman Visualizer

Amid the global response to the COVID-19 pandemic, the Postman team has played a vital role by developing a crowdsourced COVID-19 API Resource Center, aimed at providing easier access to and understanding of public data. This initiative includes a tutorial on using Postman Visualizer to create visual representations of COVID time series data within the Postman app, which guides users through importing an example collection and using JavaScript and HTML to enhance data visualization. By employing the Handlebars templating engine and integrating Chart.js, users can transform raw API data into interactive and informative visualizations, such as line graphs, to better comprehend trends over time. The tutorial encourages further exploration and customization by suggesting enhancements like styling with CSS, adding interactivity, and comparing datasets, thereby empowering users to leverage data visualization for deeper insights and effective communication.
