Increasingly in basic research and many other sectors, there is a need for quick-look visualization of large datasets in order to (a) conceptualize the nature of the data, and (b) begin identifying data patterns to guide more computationally costly deep-dive analysis. High-end tools for data basing and graphing exist, but usually entail a large overhead in time and effort associated with: importing the data; correctly specifying meta-data; keeping track of a large number of variable names; issuing and scripting commands for graphing; plotting pairwise variables over many iterations; filtering out bad data; re-rendering plots to restricted data ranges; representing multiple variables at once; and so on. This team has developed Filtergraph, a web based tool that allows rapid and intuitive visualization of massive, multi-dimensional datasets. The web-based tools developed by this team will allow researchers to instantly visualize any dataset in many dimensions at once, and will permit researchers to move through the data rapidly, and quickly filter and slice them. This visual interaction will occur without the need for cumbersome meta-data specification, without the need to remember details of the data structure, and without the need to write scripts to render sophisticated visualizations. The tools developed will be a means to an end: A new, highly visual way of transcending preconceptions about the data and instead let the data speak for themselves. This mechanism would free researchers to creatively and collaboratively engage their expert intuition as they visually and rapidly explore massive datasets for unexpected patterns or outliers that signal important discovery.

在基础研究和许多其他领域，越来越需要快速查看大型数据集的可视化，以便 (a) 概念化数据的性质，以及 (b) 开始识别数据模式以指导计算成本更高的深入研究分析。 存在用于数据基础和绘图的高端工具，但通常会在以下方面产生大量时间和精力开销：导入数据；正确指定元数据；跟踪大量变量名称；发出绘图命令并编写脚本；在多次迭代中绘制成对变量；过滤掉不良数据；将绘图重新绘制到受限的数据范围；一次表示多个变量；等等。该团队开发了 Filtergraph，这是一种基于网络的工具，可以快速直观地可视化大量多维数据集。该团队开发的基于网络的工具将允许研究人员立即在多个维度上可视化任何数据集，并允许研究人员快速浏览数据，并快速过滤和切片它们。这种视觉交互不需要繁琐的元数据规范，不需要记住数据结构的细节，也不需要编写脚本来呈现复杂的可视化效果。开发的工具将成为达到目的的一种手段：一种新的、高度可视化的方式，超越对数据的偏见，让数据自己说话。这种机制将使研究人员能够创造性地、协作地利用他们的专家直觉，以直观方式快速探索大量数据集，以寻找标志着重要发现的意外模式或异常值。
