Day 15 of learning Data Science as a beginner. Topic: Introduction to data visualisation. Psychology says that people prefer skimming over reading large paragraphs i.e. we don't like to read large texts rather we prefer something which can give us quick insights and that's when data visualisation comes in. Data visualisation is the graphical presentation of boring data. it is important because it helps us quickly take insights from large data sets and also allows us to see patterns which would have otherwise been omitted or ignored. data visualisation also helps in communication of insights to all people including those with limited technical knowledge and this not only makes the whole process more visual and engaging but also helps in fast decision making. There are some basic principals for good data visualisation. Clarity: avoid clutter and use labels, legends, and proper labeling for better communication. Context: always provide context about what is being measured? Over what time frame? and in what units? Focus: it is always a good idea to highlight the key insights by using colors and annotations. Storytelling: don’t just show data — tell a story. Guide the viewer through a narrative. Accessibility: use color palettes that enhance readability for all viewers.
