This example demonstrates how to reorder the columns of a pandas DataFrame based on a custom index sequence. It first extracts the existing column names into a list, then uses list comprehension to select columns by their numeric positions—specifically indices 3, 2, 1, 4, 6, 4, and 8—creating a new DataFrame with the rearranged order. The code relies on pandas’ column indexing and list slicing to perform the reordering.

import reorder.js

This example demonstrates how the `reorder.js` library's `barycenter_order` algorithm reorders the rows and columns of an adjacency matrix to reveal clustered structure in a network. It first converts a small binary matrix into a graph via `mat2graph`, then applies the permutation to the transposed matrix. The code also loads edge-list data from `infect-dublin.edges`, suggesting the technique scales to real-world network datasets.

This example highlights differences between two pandas DataFrames by key. It displays the two records side-by-side, transposing them into a single table where each column represents a field. Any column containing differing values between the two rows is visually marked with a yellow background. The implementation uses the pandas `DataFrame.style.apply` method to apply a custom `highlight_diff` function that checks for uniqueness across the row pairs, returning conditional formatting styles for the table.

ternary applied to fix a np.column with some nulls based on index

This example repairs missing values in a pandas DataFrame column by applying a ternary logic based on the DataFrame’s index. The code defines a function `f` that takes an index value `i` and returns a replacement, then constructs a pandas Series `s` by calling `f(i)` for every index entry via a list comprehension. Using `np.where` from NumPy, it checks whether each original value in column `'A'` is not null; if true, it keeps the original value, otherwise it substitutes the corresponding value from the generated Series `s`. The visualization demonstrates a data-cleaning pattern where null entries are filled programmatically rather than through interpolation or dropna, highlighting the interplay between pandas Series operations and NumPy’s conditional array selection.

Order

This example demonstrates how a user can reorder a list of five items (A–E) through clicks. The initial list is rendered as an HTML `<ul>` using D3’s `d3.select` and `selectAll` chains, with each item bound to the first row of a hardcoded 5×5 string array. Clicking an item triggers the `reorder` function, which calls `.data()` on the existing `li` nodes with that click’s corresponding row, then applies D3’s `.order()` to smoothly animate the reordered elements.

This example shows a data-cleaning pipeline for an Instagram influencer dataset, highlighting the number of unique users and missing values across key columns. The code uses pandas to inspect and transform the data, filling missing industry labels with "General," dropping rows without captions, removing duplicate entries, and converting the post date column to datetime format for time-series indexing. The visualization relies on pandas' built-in data manipulation functions, such as `fillna`, `drop_duplicates`, and `set_index`, rather than a plotting library. The final output would be a cleaned dataframe ready for trend analysis, though no chart is generated in the provided script.

This example displays a pandas DataFrame table listing 14 unique superpowers alongside their corresponding heroes, such as Kool-Aid Man’s Thirstokinesis and Dr. Manhattan’s Molecular Dissipation. The code constructs the table from a Python dictionary using `pd.DataFrame.from_dict`, rendering the data as an HTML table with styled headers and row indices. The output is a static, text-based visualization of the one-to-one mapping between each distinct ability and its associated character, with no charts or graphical elements involved.

Draggable Y-axis

This D3.js (v5) example demonstrates how to reorder a categorical axis by dragging its labels. It displays a draggable list of four Iris flower feature names (sepal length, sepal width, petal length, petal width) in a fixed-position panel. Users can drag and drop each item to change its position, which updates the underlying `axis` array. The implementation uses native HTML5 drag-and-drop events (`dragstart`, `dragover`, `drop`) and DOM manipulation to swap list items, providing a simple interface for interactive axis reordering.

selection.order

This example demonstrates how `selection.order` reorders DOM elements to match the order of their bound data. Three initial divs are created from an array, then the selection is re-bound to a longer array with a key function. New divs are appended for entering elements, and `div.order()` repositions all divs so their document order matches the data order. The code uses d3.v3 with basic selections, data joins, and the `text` operator, showing a simple before-and-after ordering effect.
