Abstract:

Large volumes of data generated through sensor-rich, sentient environments have produced an unprecedented landscape for analysis, namely big data. Both public and private sectors increasingly mine these data streams to guide service delivery, shape policy, and develop strategic initiatives, often relying on algorithmic processing and, more recently, artificial intelligence. While vast data sets promise insight, their scale also complicates the identification of meaningful patterns. Data Visualization has emerged as a pivotal tool not only for communicating results but also for supporting early-stage analytical inquiry. This presentation examines how visualization techniques can facilitate first-glance assessments of large data sets, enabling researchers to detect significant tends that merit deeper investigation. Visualization can function as an incipient methodological step – an interpretive bridge that helps make sense of complexity before more targeted analyses are undertaken. This presentation will draw on concrete examples, including GIS_based open-source dashboards in smart-city initiatives, geo-visualization tools, participatory planning interfaces, and 3D urban analytics, among others. Collectively, these examples illustrate how visualization practices expand the methodological repertoire available for studying phenomena in an era defined by data abundance. The presentation will also delve into the definition of big data and expand our understanding of its characteristics: volume, velocity, variety, veracity, and value as large, complex, and continuously generated datasets.
