    of declarative relational algebra like queries The DVMS logically manages the entire visualizations process from data processing to the pixels presented to the user within a single data model This allows DVMS to be both expressive via the visualization language performant by leveraging traditional and visualization specific optimizations to scale interactive visualizations to massive datasets and maintainable by enabling more powerful analysis tools Mappings of Interactions Mappings of Interactions is a declarative approach to interaction specification realized through a language called DDI DDI is intended to radically simplify the specification of interactive visualizations enabling much more widespread use of interactive features The dynamics of interaction introduce unique technical challenges and opportu nities including debugging and testing of asynchronous interaction handlers and design tradeoffs between scaling up data and maintaining interface responsiveness We hypothesize that the Mappings of Interactions can make these classes of challenges much more tractable and that DDI can engage visualization designers in widespread creative development of new interactive visualizations Perceptually Accurate Interactive Visualizations An often overlooked element of the interactive data visualization stack is the human in the loop While computational and data processing capabilities have increased over time human limits have remained constant In this light

    be installed using pip pip install dbwipes Check out the github page for code and usage instructions Scorpion Consider a simple analytic query that computes a company s total expenses by month and shows that last month s expenses was unexpectedly high The analyst will naturally want to understand why perhaps the company has put more resources into a new customer demographic or a department is overspending Currently the analyst must manually split the input data along different dimensions e g dept customer age and hope that re running the query will cause changes If there is more than one outlier or many dimensions in the dataset this ad hoc process quickly becomes untenable Scorpion is a library that helps answer these why questions The user simply selects examples of outlier and normal results and Scorpion will look for subsets of the input table that potentially explains the outliers and finds a combination of attribute values predicate that describes that subset To find such predicates we develop a score for how much influence a predicate on the outliers and design efficient algorithms to find predicates with lots of influence Get Scorpion Scorpion is a python library that can be installed
