**What kind of graph or chart does this image represent? **

**Which kind of graph is made of pictures?** A picture graph, or pictograph, is a graph used to display information that uses images or symbols to represent data.

**How do you describe a picture graph?** A picture graph is a pictorial display of data with symbols, icons, and pictures to represent different quantities. The symbols, icons, and pictures of a picture graph typically represent concepts or ideas, or stand in for a larger quantity of something. They used pictures known as hieroglyphics to convey a message.

**What is chart and its types?** A chart is a graphical representation for data visualization, in which “the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart”. A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data.

Three types of graphs are used in this course: line graphs, pie graphs, and bar graphs. Each is discussed below.

An image is a composite data type. An image file is typically a binary format file. Trying to display a binary file as text won’t often give you anything of value.

As nouns the difference between diagram and chart

is that diagram is a plan, drawing, sketch or outline to show how something works, or show the relationships between the parts of a whole while chart is a map.

A pictograph is the representation of data using images. Pictographs represent the frequency of data while using symbols or images that are relevant to the data. This is one of the simplest ways to represent statistical data.

In Statistics, pictographs are charts that are used to represent data using icons and images relevant to the data. A key is often included in a pictograph that indicates what each icon or image represents.

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

A tally chart is a simple way of recording and counting frequencies. Each occurrence is shown by a tally mark and every fifth tally is drawn diagonally to make a “gate” of five. The tallies can then be counted to give the frequency.

Graphs and charts condense large amounts of information into easy-to-understand formats that clearly and effectively communicate important points. Bar graphs, line graphs, and pie charts are useful for displaying categorical data. Continuous data are measured on a scale or continuum (such as weight or test scores).

Graphs and charts are visuals that show relationships between data and are intended to display the data in a way that is easy to understand and remember. People often use graphs and charts to demonstrate trends, patterns and relationships between sets of data.

A bar chart represents data categories using vertical or rectangular bars that are proportional to numerical values. It highlights the relationship between data groups and statistical values. A bar graph details changes in data groups over time. A bar chart shows the frequency of each data category.

The four basic graphs used in statistics include bar, line, histogram and pie charts.

A digital image is represented in the imaging and computer system by numbers in the form of binary digits, called bits. Here we see the general structure of a digital image. First, it is divided into a matrix of pixels. Then, each pixel is represented a series of bits.

A: In digital imaging, a pixel(or picture element) is the smallest item of information in an image. Pixels are arranged in a 2-dimensional grid, represented using squares. Each pixel is a sample of an original image, where more samples typically provide more-accurate representations of the original.

Image data is most often used to represent graphic or pictorial data. The term image inherently reflects a graphic representation, and in the GIS world, differs significantly from raster data.

All graphs are a diagram but not all diagrams are graph. This means that diagram is only a subset of graph. Graph is a representation of information using lines on two or three axes such as x, y, and z, whereas diagram is a simple pictorial representation of what a thing looks like or how it works.

If you have nominal data, use bar charts or histograms if your data is discrete, or line/ area charts if it is continuous. If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. If you want to compare volumes, use an area chart or a bubble chart.

A Pictograph represents data through pictures of objects.

Graphic representation is another way of analysing numerical data. 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. Graphs enable us in studying the cause and effect relationship between two variables.

A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.

A line graph reveals trends or progress over time and can be used to show many different categories of data. You should use it when you chart a continuous data set.

A tally chart is a table used for counting and comparing the numbers of multiple classes of a data set. A tally chart is just one method of collecting data using tally marks. This data can then be used to create more detailed and visual graphs and charts to compare the information that has been collected.
