Data visualization is the process of transforming data into graphical representations, such as charts, graphs, and maps.
It is a powerful tool for understanding complex data sets and making informed decisions.
Data visualization techniques can be used to explore relationships between variables, identify patterns, and gain insights into data.
Common data visualization techniques include bar charts, line graphs, scatter plots, histograms, and pie charts.
Bar charts are used to compare values across categories.
They are useful for displaying the distribution of data and comparing values between different groups.
Line graphs are used to show trends over time.
They are useful for tracking changes in data over time and identifying patterns.
Scatter plots are used to show the relationship between two variables.
They are useful for exploring correlations between variables and identifying outliers.
Histograms are used to show the distribution of data.
They are useful for understanding the spread of data and identifying clusters.
Pie charts are used to show the proportion of data in each category.
They are useful for understanding the relative size of each category.
