Ogive Graph01:07

Ogive Graph

5.9K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

Graphing the Wave Function01:13

Graphing the Wave Function

2.2K
Consider the wave equation for a sinusoidal wave moving in the positive x-direction. The wave equation is a function of both position and time. From the wave equation, two different graphs can be plotted.

Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

76
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Manipulation and Analysis

72
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

States of Water01:23

States of Water

54.0K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Levels of Use of a GIS01:29

Levels of Use of a GIS

110
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

    Area of Science:

    • Graph theory
    • Data visualization
    • Network analysis

    Background:

    • Graphs are fundamental data structures, but visualizing large-scale graphs remains challenging.
    • Existing methods struggle with interpretability and scalability for massive networks.

    Purpose of the Study:

    • To introduce Graph Cities, a novel 3-D visualization technique for graph partitions.
    • To enable humanly interpretable descriptions of large graphs irrespective of size.

    Main Methods:

    • Partitioning graph edges into maximal connected subgraphs (fixed points).
    • Representing subgraphs as 3-D 'Buildings' and positioning them via polylog bucketization.
    • Generating street networks using Delaunay triangulation of building locations.

    Main Results:

    • Demonstrated Graph Cities on large networks: Friendster (1.8B edges), IMDb (115M edges), patent citations (16.5M edges).
    • Efficiently generated Graph Cities for up to 2 billion edges within minutes (excluding I/O).

    Conclusions:

    • Graph Cities offer a scalable and interpretable approach to visualizing massive graphs.
    • The method facilitates understanding complex network structures across diverse domains.
