CARTA is the 'Cube Analysis and Rendering Tool for Astronomy', a new image visualization and analysis tool designed for the ALMA, VLA, SKA pathfinders, and the ngVLA. The mission of CARTA is to provide usability and scalability for the future by utilizing modern web technologies and computing parallelization. To account for large images that are hosted remotely, CARTA applies a remote server approach that is accessible from a local web-based client. A desktop version bundles the server-client structure in a single application. Our focus on performance is reflected in short, progressive loading times, with only seconds to load TB sized multi-dimensional image cubes (FITS, CASA, MIRIAD, HDF5-IDIA). The current version of CARTA (v.1.2) includes flexible coordinate transformations of images, image statistics and histograms, spatial and spectral profiles, cube animators and Stokes analysis, regions of interest and configurable layouts. World-coordinate support for image overlays and a scripting language are some of the core functionalities that are currently under development.
