问题     There are many kinds of graphs that can be used to show information. Another name for information is data. Graphs make reports and science research more powerful. They let us see with our eyes what the numbers actually mean. They bring the numbers to life so we can analyze them. We can look at the results and understand them better.
    You choose a graph depending on what you want to show. Certain kinds of graphs are better than others to make information stand out. When you have data to include in a report or presentation, choose the one that fits your data best.
    A pie chart is good for showing a part of a whole. A line graph is an excellent choice if you want to describe how something changes over time. It is also good for showing big differences. Use it to compare the highest and lowest numbers or the shortest and tallest plants. Data is represented with pictures or symbols on a pictograph(统计图表). Each picture or symbol can represent whatever number of items you choose. A colorful bar graph can show changes over time. You can also use it to make comparisons between two or more things. A Venn diagram (韦恩图) uses two circles. They are perfect for sorting information. You can use them to sort plants, for example. Plants with green leaves go on the left. Plants with flowers go on the right. Plants with both go in the middle where the circles overlap(重叠). Choosing the right graph can help you create a better project. Your data will be displayed clearly for others to understand.
