Sorry, there was a problem loading this page. Noble Desktop is todays primary center for learning and career development. The best way to do it will be by using heatmaps. Fortunately, the Boston dataset has 0 null values. However, conducting a thorough EDA is important to get a better sense of what your data looks like and ensure there are no outliers or missing values that might skew your analysis. Within Python, many libraries exist: Matplotlib : probably the most standard and most widely used Seaborn : high-level interface to Matplotlib, statistical functions built in Altair : declarative visualization (R users will be more at home), statistics built in Plotly : interactive graphs Bokeh : also here good for interactivity We are passing these values as two parameters of the pyplot.bar () function. Lets start by importing libraries we will need to conduct some basic EDA. Matplotlib Matplotlib is an integrated python library which aims for creating visualization and graphical representation such as line chart,scatter chart,pie chart,etc. It is a type of bar plot where the X-axis represents the bin ranges while the Y-axis gives information about frequency.
