1. Bar Chart
Used for: Comparing categories of data. Each bar represents a category, and the length shows
the value for that category. Great for showcasing comparisons between things like product
sales, customer demographics, or survey results.
Consider using a bar chart when: You have a limited number of categories (usually less than 10)
and want to make clear comparisons between them.
2. Histogram
Used for: Showing the distribution of
data points within a continuous range.
Think of it like a bar chart turned
sideways. Each bar represents a range of
values (called a bin), and the height
shows how many data points fall within
that range. Useful for understanding
how data spreads out.
Consider using a histogram when: You
have a continuous variable (like height,
weight, or temperature) and want to see
how it's distributed.
3. Line Chart
Used for: Showing trends over time or along a continuous variable.
Lines connect data points, allowing you to visualize changes over a
period. Great for tracking stock prices, website traffic, or
temperature fluctuations.
Consider using a line chart when: You have data points collected over
time or along a continuous variable and want to see how the values
change.
4. Area Chart
Used for: Similar to line charts, but the area under
the line is filled with color. This emphasizes the
magnitude of change over time and can be useful
for visualizing quantities.
Consider using an area chart when: You want to
show trends over time or along a continuous
variable, with a focus on the total value
accumulated.
5. Surface Chart
Used for: Displaying data with three dimensions (X, Y, and Z). Useful for visualizing complex
relationships between variables, often in scientific or engineering fields.
Consider using a surface chart when: You have three-dimensional data and need to visualize how
one variable changes based on the other two.
6. Treemap
Used for: Representing hierarchical data structures. Boxes
are nested within each other, showing how categories are
related and their sizes relative to the whole. Great for
visualizing file system organization, product categories, or
company structures.
Consider using a treemap when: You have data with a
hierarchical structure and want to show how parts relate to
the whole, with a focus on size comparisons.
7. Box and Whisker Chart
Used for: Summarizing the distribution of data within categories. The box shows the quartiles
(25th, 50th, and 75th percentiles), and whiskers extend to show the range of data points outside
the box. Useful for comparing distributions between groups and identifying outliers.
Consider using a box and whisker chart when: You want to compare the distribution of data
across different categories and identify potential outliers.
