Circos A free (GPL) software package from Canada for data visualization in a circular layout. Written in Perl. Effective for big datasets in high dimensions, particularly with spatial relationships.
Filtergraph An interactive portal for fast display of large multivariate datasets. Capabilities include scatter plots, histograms and tables with zoom, rotation, filtering, sorting, sharing, and flexible I/O. Developed by the Vanderbilt Initiative in Data-Intensive Astrophysics.
imMens A system designed to support interactive visual exploration of large (billion-element) datasets of several types (ordinal, numeric, temporal, geographic). Provides interactive brushing and linking, low dimensional projects, and rendering. Developed in 2013 by the Stanford Vis Group.
LCanimator A visualizer of univariate time series as a movie of the data `assembling' over time. Developed by the Vanderbilt Initiative in Data-Intensive Astrophysics.
Viewpoints A high-performance, interactive, exploratory analysis tool for large high-dimensional data. Its primary functionality is linked scatter plots with brushing for samples up to 107 rows and 102 columns that fit into CPU memory. Developed at NASA-Ames, it is available here.
yt A Python-based analysis and visualization package for volumetric, multi-resolution data. It is designed to visualize products of astrophysical theory such as hydrodynamical calculations allowing slices, projections, volume rendering, and multivariate maps.

ColorBrewer 2.0 Color advice for cartography. Provides dozens of recommended color schemes for filling contour maps and displaying two-dimensional structures. Designations in RGB, CMYK and HEX color systems are provided.
Color Hex Color Codes Color-hex.com gives information about colors including color models (RGB,HSL,HSV and CMYK), Triadic colors, monochromatic colors and analogous colors calculated in color page. Includes Popular Color Palettes, Latest Users Favourite Colors and >500 Color Names (e.g. DarkSeaGreen4 = #698b69).
HCL-Based Color Palettes Hue-Chroma-Luminance (HCL) is a perceptually-based color space discussed here that is well-designed for statistical graphics. It is implemented for the R software system in the CRAN package colorspace.
