ColorBrewer
ColorBrewer is an online tool for selecting map color schemes based on palettes created by Cynthia Brewer. It was launched in 2002 by Brewer, Mark Harrower, and The Pennsylvania State University. Suggested color schemes are based on data type (sequential, diverging, or qualitative). It also provides options for varied display environments, such as laptop, photocopy, and LCD projector, and colorblind safe options. ColorBrewer is licensed using Apache 2.0 software license, which is similar to CC-BY-SA 3.0. Brewer palettes Valid names and a full color representation for each palette are shown below. If this is viewed in a compliant browser, moving the mouse cursor over each box will pop up the corresponding color number as a tooltip. *YlGn *YlGnBu *GnBu *BuGn *PuBuGn *PuBu *BuPu *RdPu *PuRd *OrRd *YlOrRd *YlOrBr *Purples *Blues *Greens *Oranges *Reds *Greys *PuOr *BrBG *PRGn *PiYG *RdBu *RdGy *RdYlBu *Spectral *RdYlGn *Accent *Dark2 *Paired *Pastel1 *Pastel2 *Set1 ...

Warming Stripes
Warming stripes (sometimes referred to as climate stripes, climate timelines or stripe graphics) are data visualization graphics that use a series of coloured stripes chronologically ordered to visually portray long-term temperature trends. Warming stripes reflect a "minimalism, minimalist" style, conceived to use colour alone to avoid technical distractions to intuitively convey global warming trends to non-scientists. The initial concept of visualizing historical temperature data has been extended to involve animation, to visualize sea level rise and predictive climate data, and to visually juxtapose temperature trends with other data such as atmospheric concentration, global glacier retreat, precipitation, progression of ocean depths, and Environmental effects of aviation, aviation emission's percentage contribution to global warming. Background, publication and content In May 2016, to make visualizing climate change easier for the general public, University of Reading ...

Map Coloring
In cartography, map coloring is the act of choosing colors as a form of map symbol to be used on a map. In mathematics, map coloring is the act of assigning colors to features of a map such that no two adjacent features have the same color using the minimum number of colors. Cartography Color is a very useful attribute to depict different features on a map. Typical uses of color include displaying different political divisions, different elevations, or different kinds of roads. A choropleth map is a thematic map in which areas are colored differently to show the measurement of a statistical variable being displayed on the map. The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region. In addition to choropleth maps, a cartographer should strive to depict colors effectively on any kind of map. Displaying the data in different hues can greatly affect the understanding or feel of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Choropleth Map
A choropleth map () is a type of statistical thematic map that uses pseudocolor, i.e., color corresponding with an aggregate summary of a geographic characteristic within spatial enumeration units, such as population density or per-capita income. Choropleth maps provide an easy way to visualize how a variable varies across a geographic area or show the level of variability within a region. A heat map or isarithmic map is similar but uses regions drawn according to the pattern of the variable, rather than the ''a priori'' geographic areas of choropleth maps. The choropleth is likely the most common type of thematic map because published statistical data (from government or other sources) is generally aggregated into well-known geographic units, such as countries, states, provinces, and counties, and thus they are relatively easy to create using GIS, spreadsheets, or other software tools. History The earliest known choropleth map was created in 1826 by Baron Pierre Charles D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Pennsylvania State University
The Pennsylvania State University (Penn State or PSU) is a Public university, public Commonwealth System of Higher Education, state-related Land-grant university, land-grant research university with campuses and facilities throughout Pennsylvania. Founded in 1855 as the Farmers' High School of Pennsylvania, Penn State became the state's only Land-grant university, land-grant university in 1863. Today, Penn State is a major research university which conducts teaching, research, and public service. Its instructional mission includes undergraduate, graduate, professional and continuing education offered through resident instruction and online delivery. The University Park campus has been labeled one of the "Public Ivy, Public Ivies", a publicly funded university considered as providing a quality of education comparable to those of the Ivy League. In addition to its land-grant designation, it also participates in the sea-grant, space-grant, and sun-grant research consortia; it is on ...

Colorblind
Color blindness or color vision deficiency (CVD) is the decreased ability to see color or differences in color. It can impair tasks such as selecting ripe fruit, choosing clothing, and reading traffic lights. Color blindness may make some academic activities more difficult. However, issues are generally minor, and the colorblind automatically develop adaptations and coping mechanisms. People with total color blindness (achromatopsia) may also be uncomfortable in bright environments and have decreased visual acuity. The most common cause of color blindness is an inherited problem or variation in the functionality of one or more of the three classes of cone cells in the retina, which mediate color vision. The most common form is caused by a genetic disorder called congenital red–green color blindness. Males are more likely to be color blind than females, because the genes responsible for the most common forms of color blindness are on the X chromosome. Non-color-blind fem ...

Tooltip
The tooltip, also known as infotip or hint, is a common graphical user interface (GUI) element in which, when hovering over a screen element or component, a text box displays information about that element, such as a description of a button's function, what an abbreviation stands for, or the exact absolute time stamp over a relative time ("… ago"). In common practice, the tooltip is displayed continuously as long as the user hovers over the element or the text box provided by the tool. It is sometimes possible for the mouse to hover within the text box provided to activate a nested tooltip, and this can continue to any depth, often with multiple text boxes overlapped. On desktop, it is used in conjunction with a cursor, usually a pointer, whereby the tooltip appears when a user hovers the pointer over an item without clicking it. On mobile operating systems, a tooltip is displayed upon long-pressing—i.e., tapping and holding—an element. Some smartphones have alternati ...
