The diagrams illustrate some changes to a small island which has been developed for tourism. It is clear that the island has changed considerably with the introduction of tourism‚ and six new features can be seen in the second diagram. The main developments are that the island is accessible and visitors have somewhere to stay. Looking at the maps in more detail‚ we can see that small huts have been built to accommodate visitors to the island. The other physical structures that have been added are

Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs

The bar chart illustrates the unemployment rate in Germany compared to the unemployment rate in Ireland. The y-axis shows the rate of unemployment which is defined by the number of unemployed persons as a percentage of the labor force. On the x-axis you can read the year. In 2000‚ 8 per cent of the German workforce was unemployed‚ which was twice as high as Ireland. Unemployment in Germany declined slightly in 2001. However‚ after this the unemployment rate rose steadily over the next four years

We don’t say data structurehere and see the difference. Graphs mean to store and analyze metadata‚ the connections‚ which present in data. For instance‚ consider cities in your country. Road network‚ which connects them‚ can be represented as a graph and then analyzed

The usage of graphs are essential in the illustration and comprehension of statistical output. They type of graphs used depends on the author and the view they are trying to portrait. Graphs can be used to prove or disprove a theory based on its presentation. The Following graph is used as a visually depiction of a sample of grade school childern of whom an IQ exam was performed. Figure: The histogram figures shown are extracts of an IQ test performed on elementary school subjects and

Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

DESCRIBING GRAPHS AND CHARTS The function of a line graph is to describe a TREND pictorially. You therefore should try and describe the trend in it. If there are many lines in the graph(s)‚ then just generally describe the trend. If there is only one or two‚ then use more detail. So‚ describe the movement of the line(s) of the graph giving numerical detail at the important points of the line. To describe the movement‚ there is some language which will always be useful. Below is a list of language
