This page shows an interactive parallel coordinate plot for exploring multivariate data. It uses a combination of SVG elements and HTML Canvas via the d3.js library to support larger files than SVG graphics can support alone.
Use the 'Choose CSV File' button to open a local CSV formatted text file. Columns are automatically parsed using d3.js auto typing. Date, numeric, and Boolean data types are shown as axes in the parallel coordinate plot. Columns of other data types are ignored.
Sample files can be shown from the 'Load Sample Data' button.
Lines in the plot can be selected by dragging ranges on any of the axes.
The 'Redraw' button can be used to regenerate the plot. If the window is resized, regenerating the plot will adjust the chart widths to fill the available space.
The 'Settings' button can be used to control several visual parameters of the charts.
