Pie chart Pie chart of populations of English native speakers Pie charts are very widely used in the business world and the mass media.[3] However, they have been criticized,[4] and many experts recommend avoiding them,[5][6][7][8] pointing out that research has shown it is difficult to compare different sections of a given pie chart, or to compare data across different pie charts. Pie charts can be replaced in most cases by other plots such as the bar chart. Example[edit] A pie chart for the example data. The following example chart is based on preliminary results of the election for the European Parliament in 2004. *Because of rounding, these totals do not add up to 100 and 360. The size of each central angle is proportional to the size of the corresponding quantity, here the number of seats. Use, effectiveness and visual perception[edit] An example of a pie chart with 18 values, having to separate the data from its representation. Variants and similar charts[edit] Exploded pie chart[edit] Notes[edit]

Flowchart Software Review 2012 | Best Flowcharting Software | Flowchart Diagram Software - TopTenREVIEWS Radial tree Example of a radial tree, from a 1924 organization chart that emphasizes a central authority.[1] Radial vs. triangular tree layout Comparison to other layouts[edit] In a simple case, the first node is at the top, and the linked nodes are beneath. Since the length of each orbit increases with the radius, there tends to be more room for the nodes. Basic layout[edit] The overall distance "d" is the distance between levels of the graph. The layout has some similarities to a hyperbolic tree, though a key difference is that hyperbolic trees are based on hyperbolic geometry, whereas in a radial tree the distance between orbits is relatively linear. Examples[edit] MindManager and MindMapper are mindmapping systems, which can make radial-like layouts, though are not radial beyond the 2nd level.SpicyNodes is an approach to visualizing hierarchies, which allows moving from node to node.

Workflow A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information.[1] It can be depicted as a sequence of operations, declared as work of a person or group,[2] an organization of staff, or one or more simple or complex mechanisms. Workflows may be viewed as one fundamental building block to be combined with other parts of an organisation's structure such as information silos, teams, projects, policies and hierarchies.[5] Historical development[edit] The development of the concept of workflow occurred over a series of loosely defined, overlapping, eras. Beginnings in manufacturing[edit] The modern history of workflows can be traced to Frederick Taylor[6] and Henry Gantt. Information-based workflows began to grow during this era, although the concept of an information flow lacked flexibility. Maturation and growth[edit] Quality era[edit]
Dia Welcome to Dia's homepage. Dia is a GTK+ based diagram creation program for GNU/Linux, MacOS X, Unix, and Windows, and is released under the GPL license. Dia is roughly inspired by the commercial Windows program 'Visio,' though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape. It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to a number of formats, including EPS, SVG, XFIG, WMF and PNG, and can print diagrams (including ones that span multiple pages). Download Dia and try using it; tell us what you think of it (visit the Contact page), including to report bugs if you find them. CategoryGraphics
Diagram A diagram is a two-dimensional geometric symbolic representation of information according to some visualization technique. Sometimes, the technique uses a three-dimensional visualization which is then projected onto the two-dimensional surface. The word graph is sometimes used as a synonym for diagram. Overview[edit] The term diagram in common sense can have a general or specific meaning: In the specific sense diagrams and charts contrast computer graphics, technical illustrations, infographics, maps, and technical drawings, by showing "abstract rather than literal representations of information".[1] The essences of a diagram can be seen as:[1] a form of visual formatting devicesa display that do not show quantitative data or [numerical], but rather relationships and abstract informationwith building blocks such as geometrical shapes connected by lines, arrows, or other visual links. Main diagram types[edit] There are at least the following types of diagrams: Specific diagram types[edit]
Designing programs with flow charts Designing programs with flow charts After completing this lesson you should be able to: There are some exercises for you to do and each exercise has a sample answer: Exercise 1 - a first flow chartExercise 2 - a flow chart with subprocessesExercise 3 - an advanced flow chart exerciseExercise 4 - comparing flow charts and pseudocode When you have finished the lesson you might like to attempt these questions to assess how much you have learned. Return to the indexGo to the next lessonReturn to the previous lesson What is a flow chart? Step-form and pseudocode program designs are both text-based, the statements are written. the sequence symbol,the decision symbol,the decision construct if ... thenthe decision construct if ... then ... elsethe repetition construct - repeat,the repetition construct - while, there are other symbols but the real work is depicted by the two symbols and the constructs. The language of flow charts Repeat loop. Is a repeat loop a good idea in this case? While loop. P.O.
Future - Science & Environment - Drake equation: How many alien civilizations exist? Are we alone? It is a question that has occupied mankind for centuries. Today, we live in an age of exploration, where robots on Mars and planet-hunting telescopes are beginning to allow us to edge closer to an answer. While we wait to establish contact, one technique we can use back on Earth is an equation that American astronomer Frank Drake formulated in the 1960s to calculate the number of detectable extraterrestrial civilizations may exist in the Milky Way galaxy. It is not a rigorous equation, offering a wide range of possible answers. Until ground-based observations, space telescopes and planet-roving robots uncover any tell-tale signs of life, what better way to speculate on how many intelligent alien civilizations may exist than to explore the universe with our interactive version of the equation.
