Browser-embedded visualizations have become a ubiquitous tool for sharing and exploring data. This presentation will provide an entry point to help developers choose the right tools and techniques for creating effective web-based visualizations using JavaScript APIs. We will discuss the capabilities, limitations, drawbacks, and benefits of web-based visualizations and several specific APIs (Plotly.js, d3, HTML5-Canvas, ESRI JS-API). Several use-cases will be demonstrated and the underlying code will be discussed. All code/resources will be made available for download. Attendees will leave with an understanding of how web technology can be used to visualize data, a familiarity with some popular JS-APIs, and a clear path forward to start visualizing their data in the web browser.
