Splom
Overview
The splom
trace type is used to create scatter plot matrices, which are useful for visualizing pairwise relationships between multiple variables. A scatter plot matrix shows scatter plots for each pair of variables, making it a great tool for exploring correlations and patterns in multi-dimensional data.
You can customize the marker size, color, and lines, similar to scatter plots, but for each pair of variables in the matrix.
Common Uses
- Pairwise Relationship Analysis: Exploring relationships between multiple variables simultaneously.
- Correlation Visualization: Identifying patterns, clusters, or outliers in high-dimensional datasets.
- Multivariate Data Exploration: Useful in statistics, machine learning, and data science for analyzing multiple variables at once.

. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%xother}, {%_xother}, {%xother_}. When showing info for several points, xother will be added to those with different x positions from the first point. An underscore before or after (x|y)other will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax.

) are available. Anything contained in tag<extra>

And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: %h for half of the year as a decimal number as well as %{n}f for fractional seconds with n digits. For example, 2016-10-13 09:15:23.456 with tickformat %H~%M~%S.%2f would display 09~15~23.46
