In this chapter, we covered six basic types of charts, namely, Time Series charts, bar charts, line charts, histograms, and scatter plots. These charts are extensively used in the data exploration phase to help us better understand our data. Visually understanding our data this way can help us easily figure out anomalies in our dataset and give us insights into our data that we can later put to use for making predictions on new data. Each chart can be used for specific needs such as:
Time Series charts show us how our data changes with respect to time
Bar charts show us the trends in our data and histograms help us find the density of our data
Box charts help us find the minimum, maximum, median values in our numerical data, and also help us figure out the outlier points
Scatter plots help us figure out patterns in our data or how our data points are concentrated
Java provides us with various open source libraries that we can put to use for making these charts. One such popular library...
