Bar charts are used to compare data along two axes.<\/h5>\n<h5>One of the axes is numerical, while the other visualizes the categories or topics being measured.<br \/>You can use a bar chart with vertical bars or horizontal bars.<\/h5>\n<h5>On vertical bar graphs, numerical values are on the y axis (vertical axis); on horizontal bars, they are on the x-axis (horizontal axis.)<br \/>To choose which style of bar graph to use, take a look at your data.<\/h5>\n<h5>If your qualitative data has long, descriptive names, then a horizontal bar chart would be the best choice. Another creative option is to use a visual axis system like in the template above.<br \/>Instead of placing the category name next to its respective bar, use a color-coding system and a legend.<\/h5>\n<h5>For a more creative approach, try using 3D bars, animated effects and photographic backgrounds.<\/h5>\n<\/details>\n<details id=\"e-n-accordion-item-9851\" >\n<summary data-accordion-index=\"2\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-9851\" >\n\t\t\t\t\t Type #2: Pie Chart<br \/>\n\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><br \/>\n\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><br \/>\n\t\t\t\t\t\t<\/summary>\n<p>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"512\" height=\"512\" src=\"https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart.png\" alt=\"\" srcset=\"https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart.png 512w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-300x300.png 300w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-150x150.png 150w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-12x12.png 12w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-410x410.png 410w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-50x50.png 50w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/p>\n<h5>The second most common data visualization on this list is the pie chart.<\/h5>\n<h5>The data in a pie chart represent parts of a whole.<\/h5>\n<h5>The entirety of the circle is the whole, and each wedge is a relevant section.<br \/>The best type of data for a pie chart has no more than five or six parts.

is one of the most common data visualizations on this list.<\/h5>\n<h5>They&#8217;re sometimes also referred to as column charts. Bar charts are used to compare data along two axes.<\/h5>\n<h5>One of the axes is numerical, while the other visualizes the categories or topics being measured.<br \/>You can use a bar chart with vertical bars or horizontal bars.<\/h5>\n<h5>On vertical bar graphs, numerical values are on the y axis (vertical axis); on horizontal bars, they are on the x-axis (horizontal axis.)<br \/>To choose which style of bar graph to use, take a look at your data.<\/h5>\n<h5>If your qualitative data has long, descriptive names, then a horizontal bar chart would be the best choice. Another creative option is to use a visual axis system like in the template above.<br \/>Instead of placing the category name next to its respective bar, use a color-coding system and a legend.<\/h5>\n<h5>For a more creative approach, try using 3D bars, animated effects and photographic backgrounds.<\/h5>\n<p>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"512\" height=\"512\" src=\"https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart.png\" alt=\"\" srcset=\"https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart.png 512w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-300x300.png 300w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-150x150.png 150w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-12x12.png 12w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-410x410.png 410w, https:\/\/certifeka-edu.com\/wp-content\/uploads\/2025\/08\/PieChart-50x50.png 50w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/p>\n<h5>The second most common data visualization on this list is the pie chart.<\/h5>\n<h5>The data in a pie chart represent parts of a whole.<\/h5>\n<h5>The entirety of the circle is the whole, and each wedge is a relevant section.<br \/>The best type of data for a pie chart has no more than five or six parts.
