TDAview is an online tool for topological data analysis (TDA) and visualization. It implements the Mapper algorithm for TDA and provides extensive graph visualization options. TDAview is a user-friendly tool that allows biologists and clinicians without programming knowledge to harness the power of TDA. TDAview supports an analysis and visualization mode in which a Mapper graph is constructed based on user-specified parameters, followed by graph visualization. It can also be used in a visualization only mode in which TDAview is used for visualizing the data properties of a Mapper graph generated using other open-source software. The graph visualization options allow data exploration by graphical display of metadata variable values for nodes and edges, as well as the generation of publishable figures. TDAview can handle large datasets, with tens of thousands of data points, and thus has a wide range of applications for high-dimensional data, including the construction of topology-based gene co-expression networks.
TDAview is a free online tool available at https://voineagulab.github.io/TDAview/. The source code, usage documentation and example data are available at TDAview GitHub repository: https://github.com/Voineagulab/TDAview.
TDAview 是一个用于拓扑数据分析（TDA）和可视化的在线工具。它实现了 Mapper 算法用于 TDA，并提供了广泛的图形可视化选项。TDAview 是一个用户友好的工具，允许没有编程知识的生物学家和临床医生利用 TDA 的强大功能。TDAview 支持分析和可视化模式，其中根据用户指定的参数构建 Mapper 图，然后进行图形可视化。它也可以仅用于可视化模式，其中 TDAview 用于可视化使用其他开源软件生成的 Mapper 图的数据属性。图形可视化选项允许通过图形显示节点和边的元数据变量值来进行数据探索，并生成可发布的图形。TDAview 可以处理具有数千个数据点的大型数据集，因此在高维数据方面有广泛的应用，包括基于拓扑的基因共表达网络的构建。
