Diagrammatic representation can be used for both the educated section and uneducated section of the society. We can use another way of diagrammatical representation of data. Typically, a graph shows the unreasonable tendency of the data and the actual values are not clear. We can locate a point in a plane using two mutually perpendicular lines-the X-axis (the horizontal line) and the Y-axis (the vertical line). The viewer does not require prior knowledge of mathematics or statistics to understand a graph. In the words of M.J.

A diagrammatic language, as John Walker explains, employs a variety of means to encode information and every single element inside the map has a specific function. In graphs, it is represented using two lines called coordinate axes. The transformation of data through visual methods like graphs, diagrams, maps and charts is called representation of data. In absolute figures, comparisons may not be clear but when it comes to talk about Diagrammatic Presentation, well it tell comparison between two or more sets of data.

The horizontal axis is denoted as the x-axis and the vertical axis is denoted as the y-axis. All geographic variation is then expressed by assigning properties or attributes to these cells. The transformation of data through visual methods like graphs, diagrams, maps and charts is called representation of data. These can be represented either vertically or horizontally. Usually, graphs are used to present time series and frequency distributions. The point where the perpendiculars intersect is the position of the point P. We denote it as follows (3, 5) or (abscissa, ordinate). Such a form of the presentation of data makes it easy to understand the patterns of population growth, Diagram provide simple and attractive way to present with data.

Ends … Analyzing map legends to better understand the nature of the representation of data on the map (e.g., classification values and break points of a choropleth map, methods for determining different classification values, review the histogram of the data to see how data are represented in another form in addition to the mapped version). Learn vocabulary, terms, and more with flashcards, games, and other study tools. For example, if a point P is 3 units away from the Y-axis and 5 units away from the X-axis, then its location is as follows: We measure the distance of the point from the Y-axis along the X-axis. Data may be presented in a simple &attractive manner in the form of diagrams. Data is ingested into graphical representation of data software and then represented by a variety of symbols, such as lines on a line chart, bars on a bar chart, or slices on a pie chart, from which users can gain greater insight than by numerical analysis alone. It depicts only a few selected characteristics of the data. The Generation of Schematic Diagrams from Geographic Representations of Networks Paul Yates 1 & Mark Humphreys2 Abstract Often, the geographic view of a network hides important connectivity information found in the network. 3.6.1 Raster data In a raster representation geographic space is divided into an array of cells, each of which is usually square, but sometimes rectangular (Figure 3.9). They are suitable for frequency type and non-frequency type variables such as discreet variables like grades in exams and attributes such as gender, religion, etc that can be represented with the help of a bar diagram. 12.15 Points for Discussion A graph is a sort of chart through which statistical data are represented in the form of lines or curves drawn across the coordinated points plotted on its surface. Maps, where geographical accuracy has been abandoned in favour of clarity and has been replaced by a diagrammatic language, are called diagrammatic maps. Data is ingested into graphical representation of data software and then represented by a variety of symbols, such as lines on a line chart, bars on a bar chart, or slices on a pie chart, from which users can gain greater insight than by numerical analysis alone. Raster datasets are composed of rectangular arrays of regularly spaced square grid cells. Raster datasets are composed of rectangular arrays of regularly spaced square grid cells. Therefore, to measure 3 units from the Y-axis, we move 3 units along the X-axis and likewise for the other coordinate. 10.
