Data visualization tools are software applications that allow users to create and display data in a graphical or pictorial format. They are used to explore, analyze, and communicate data, and to make it more accessible and understandable. Some common types of data visualization tools include:
-
Bar charts, line charts, and scatter plots: These tools are used to create basic charts and plots that are commonly used to display data trends over time or to compare values across different categories.
-
Heat maps and treemaps: These tools are used to display data hierarchically, such as showing the distribution of values across different regions or categories.
-
Geographic information system (GIS) software: These tools are used to create maps and display data that has a geographic component, such as showing the distribution of values across different regions or locations.
-
Dashboards and Business Intelligence (BI) software: These tools provide a way to combine different types of visualizations and data sources, such as displaying data from a database or spreadsheet in a dashboard format, that can be accessed and filtered by different users.
-
3D Visualization: These tools are used to create 3D visualizations of data and models, for example to visualize the performance of a machine learning model, or to create a 3D map of a city.
-
Open-source options: There are many open-source options for data visualization, such as Python's Matplotlib and Seaborn libraries, R's ggplot and Shiny, and JavaScript's D3.js and Chart.js.
-
Commercial options: There are also many commercial options for data visualization, such as Tableau, QlikView, and Microsoft Power BI, which provide more advanced features and support for large and complex data sets.
Two other important examples of open source data visualization tools that are commonly used and gaining traction are Vega-Lite and Bokeh. Bokeh and Vega-Lite both utilize the power of D3.js by using the Vega-Embed library, which is a JavaScript library that allows to embed Vega and Vega-Lite visualizations in web pages. Vega-Embed uses D3.js to handle the low-level details of rendering the visualization, allowing the user to focus on the design of the visualization rather than the implementation details.

Vega-Lite is an open-source visualization grammar and tool that is built on top of the Vega visualization grammar. It provides a higher-level, more concise language for creating visualizations, making it easy to create and share interactive visualizations with others. It is especially useful for creating visualizations that are easy to understand and communicate, and it can be integrated with web-based tools like Jupyter notebooks.

Bokeh is another open-source visualization library for creating interactive visualizations for modern web browsers. It is similar to Vega-Lite in that it allows users to create interactive visualizations with a simple and concise syntax. Bokeh provides a wide range of chart types and can handle large and complex data sets, it also allows to create interactive visualizations that can be embedded in web pages or Jupyter notebooks.
