This interactive word cloud visualizes opinion targets extracted from Amsterdam accommodation reviews. Word size indicates frequency of mention, while color encodes aggregated sentiment, ranging from green (positive) to red (negative) with yellow as neutral. Users can pan and zoom with the mouse. The data comes from the Tour-Pedia APIs, processed by the OpeNER sentiment analysis pipeline. The visualization uses d3.v3 with Jason Davies's d3.layout.cloud for the word layout, rendering text via SVG and canvas with animation.

AI-generated description

This word cloud shows opinion target words from reviews of accommodations in Amsterdam. Bigger words were identified more often by sentiment analyzers. Color represents the aggregated sentiment towards the target words (more green is more positive, more red is more negative and a yellow color is neutral). For example, both "hotel" and "room" have been mentioned a lot, but the overall sentiment towards "hotel" is more positive than the one towards "room".

Use the mouse to pan and zoom.

Data is obtained from the Tour-Pedia APIs, that in turn get their input from the sentiment analysis pipeline of the OpeNER project.

The implementation makes use of d3.layout.cloud by Jason Davies.

Word cloud comparison

This example compares two word clouds of hotel reviews for Amsterdam and London, using animation to transition between them while keeping word positions stable. The layout is computed once with the d3.layout.cloud plugin, using each word’s maximum weight, then per-city font size and opacity are applied, making absent words fade out. A dropdown menu triggers the update, and the SVG text elements can be panned and zoomed via mouse, with color indicating sentiment polarity. Data comes from the Tour-Pedia API via the OpeNER sentiment pipeline.

Word cloud of tweets related NYC pizza

This interactive word cloud visualizes frequently used terms from Twitter messages about NYC pizza, sampled over October and November 2014. Word size and color reflect frequency, mapping the top 100 terms from the dataset. Built with D3.js (version 3) and SVG, it places words randomly within an elliptical boundary. Users can refresh the layout or click and drag individual words to reposition them, with hover interactions that temporarily enlarge a word and change its color to blue.

Front-End for IR project

This interactive visualization front-end compares Twitter and Reddit sentiment and topic associations for user-entered words. It displays sentiment as colored, neutral, positive, or negative labels alongside word-similarity and topic-term lists. Built with D3.js v6, the interface renders SVG text and labels across a divided screen, with input fields for two words. The implementation uses custom JavaScript helper functions to map sentiment values to colors and mouth-angle symbols, while layout is managed through CSS flexbox and absolute positioning in the grid container.

WheeledDoorsAPI

This interactive visualization compares word similarity and topic distributions for two user-entered words. It renders SVG elements using D3 v6, with word lists and topic clusters positioned around a central area. The code fetches data from an AWS API Gateway endpoint via `fetch`, though it currently displays hardcoded sample data. Users can input words in text fields, and hovering over points highlights them with a blue fill. The visualization uses D3 scales and containers to arrange topic words and similarity scores in a comparative layout.

Opo Cities

The visualization depicts the geographic distribution of "opo" cities across the United States, with a dark landmass and circles sized proportionally to the number of centers in each city. Using React with D3 v5, it renders an Albers equal-area projection via `d3.geoPath`, plotting map features from the US Atlas TopoJSON and city coordinates from a CSV file. The circles’ radii are scaled by the square root of the `Centers` attribute, providing a clear comparison of city significance.

Fork of Front-End for IR project

This interactive scatterplot visualizes sentiment analysis across a corpus of text data, with each point representing a word mapped by its sentiment score and frequency. Users can enter two words into text inputs to compare their associated topics and related terms, which display as lists beside the plot. The visualization uses D3 v6 to render SVG points with hover effects that highlight individual data, while color coding indicates positive, negative, or neutral sentiment based on threshold values. The code includes fake sample data for testing, demonstrating word-topic relationships and word-word similarity rankings.

Word Cloud-3

This example displays a word cloud visualization using the d3.layout.cloud plugin, which arranges words from a TSV data file based on their frequency values. The code filters the dataset, maps each entry to a text-size pair, and uses the cloud layout with custom rotation, padding, and the Impact font. Words are rendered as SVG text elements with colors from a category20c scale, appearing animated as the layout algorithm places them across a 500×500 canvas area.

Untitled

This visualization is an adjacency matrix of email communications within the Enron corpus. Each cell represents the relationship between a sender (fromId) and a recipient (toId), with color indicating the average sentiment of their exchanged messages—orange for negative, white for neutral, and blue for positive. The matrix is rendered as an SVG using d3.v4, with `d3.scaleBand` for both axes, `d3.nest` and `rollup` to aggregate sentiment, and a linear color scale mapping sentiment values. The data comes from a CSV file containing email metadata, dates, and sentiment scores.
