Mapping the Global Supply Chain Graph

Abstract: Panjiva maps the network of global trade with unprecedented scope and granularity. Using over one billion shipping records sourced from governments around the world, we perform large-scale entity extraction and entity resolution, identifying trading relationships among millions of companies and thousands of ports, located across the world. We have developed a powerful platform facilitating search, analysis, and visualization of this network as well as a data feed integrated into S&P Global's Xpressfeed platform.

Placing supply chain networks in the familiar setting of a world map lends context that facilitates understanding of stories contained in the data. The web browser is an apt setting for creating interactive maps and geospatial applications due to the powerful inbuilt visualization and computation tools and the rich ecosystem of compatible open source libraries. Through the process of developing interactive web maps, we will learn about open source technologies for analyzing and interacting with data and explore patterns in the flow of goods between geographic areas in the global supply chain graph.

Participants will learn how to create a data driven application using React, a JavaScript web application framework. In this application, we will create interactive maps using graphics technologies SVG (scalable vector graphics) and WebGL (web graphics library) with the help of open source JavaScript libraries including D3, mapbox, and Deck.gl.
