NACIS 2016 Presentation Mamata Akella, CartoDB CARTO Builder is a powerful tool for data, analysis, and cartographic design. With an easy-to-use online interface, you can take your thematic web maps to the next level. During this talk, I will highlight how to make a variety of thematic maps from proportional symbols to dot density to the standard choropleth (and more!) all inside of our new and improved online interface. We will touch on important thematic mapping considerations including options for map types based on the characteristics of your data, projections, and enhanced options for color ramps and labeling. We will also explore other data-to-analysis-to-design methods that are now available for your next thematic web map.
