Box & Whisker plot is one of the few data visualization techniques that perform further computations on the dataset before it can be visualized. Some other methods that require calculation include a histogram, which needs a class interval and a pie chart that requires one to calculate the degree of each slice in the pie.…

One of the major setbacks of various data visualization methods is that they become increasingly difficult to read with larger datasets. The case is quite different for histograms, which is mostly used to visualize large datasets of discrete and continuous data. Histograms provide a visual representation of quantitative data by using the height of neatly joined rectangular…

Data visualization is an important aspect of data analysis, and one of the simplest methods of visualizing data is through a line graph or chart. This is partly because, for a lot of people, drawing out strokes or simple lines is quite easy to do and also not hard to interpret. That is why, when teaching children…

When studying data trends over time, we are sometimes more interested in the collectiveness of the data, rather than the individuality of each data point. In this case, an area chart or graph is used for data visualization. Area charts give a sense of summation to the quantitative data by visualizing the data in terms of the aggregate…

Data visualization using colorful dots is no doubt visually appealing and a creative statistical graphing method. But do you know something that is more visually appealing? Bubbles. Bubble charts use multiple bubbles (or circles) to display data points in a 3-dimensional space. However, the interesting thing about this 3-dimensional display is that the third dimension is…
