Date: _____________, , Assignment – 10, , Page No. _________, , Task: Write a short note about five essential plots that can help in data visualization., , Data visualization Tools, Introduction: Data visualization is the process of turning your data into graphical, representations that communicate logical relationships and lead to more informed, decision-making., In short, data visualization is the representation of data in a graphical or pictorial, format., There are five essential plots that have we need to know well for basic data visualization., , , , , , , Line Plot, Histogram Plot, Scatter Plot, Bar Chart, Box and Whisker Plot, , 1. Line Plot:, , , , , , , Input, , A line plot is used to show observations gathered at regular intervals., The x-axis shows the regular interval, such as time., The Y- axis shows the observations., A line plot can be built by the calling the plot() function and passing the X-axis data for, the regular interval, and Y – axis for the observations., # code to create a line plot, pyplot.plot(x, y), , Output

Page 15 :
2. Bar Plot:,  A bar chart presents relative quantities for multiple categories., ,  The x-axis shows the categories that are spaced evenly.,  The Y- axis shows the quantity for each category and is drawn as a bar from the, baseline to the required level on the Y-axis., ,  A bar chart can be built by the calling the bar() function and passing the category, names for the X-axis and the quantities for the Y – axis., , Input, , Output, , 3. Histogram Plot:,  Histogram plots are used for summarizing the distribution of a data sample., ,  The x-axis shows distinct bins or intervals for the observation..,  The Y- axis shows the frequency or tally of the number of observations in the dataset, that has assigned to each bin., ,  A Histogram plot can be designed by the calling the hist() function and passing a list or, array that shows the data sample., # code to create a histogram plot, pyplot.hist(x, y)

Input, , Output, , 4. Box and Whisker Plot:,  Box and whisker plot (boxplot) is usually used for summarizing the distribution of a, data sample., ,  The x-axis shows the data sample, where multiple boxplots can be created beside one, another on the X-axis., ,  The Y- axis shows the observation values.,  A box is created to summarise the middle 50% of the data set, starting at the, , observation at the 25th percentile and concluding at the 75th percentile. This is known as, interquartile range (IQR)., ,  The median or the 50th percentile , is created with a line. Lines are called whisker are, , created by extending from both ends of the box calculated as (1.5×IQR) to demonstrate, the expected range of sensible values in the distribution., ,  Observations outside the whiskers might be outliers and are drawn with small circles.,  Boxplot can be created by the calling the boxplot() function and passing in the data, sample as an array or list., # code to create a box and whisker plot, pyplot.boxplot(x, y)

Input, , Output, , 5. Scatter Plot:,  Histogram plots usually summarises the relationship between two paired data sample., ,  The x-axis shows the observation value for the first sample.,  The Y- axis shows the observation value for the second sample. Each point on the plot, shows a single observation., ,  A scatter plot can be designed by the calling the scatter() function and passing a list or, array that shows the data sample., # code to create a scatter plot, pyplot. Scatter(x, y), , Input, , Output
