This example visualizes the frequency of tweets over time, showing the number of tweets per minute from a ScraperWiki Twitter search dataset. The chart displays a histogram of tweet timestamps, with the x-axis representing dates and the y-axis showing tweet counts, capped at 40,000 tweets. The R script uses the `ggplot2` and `scales` libraries to bin the timestamps into 60-second intervals and render the plot. It queries data via ScraperWiki’s SQL interface, converts the `created_at` strings to POSIX date objects, and uses `qplot` and `ggplot_build` to construct and refine the histogram. The visualization highlights temporal activity patterns in the collected tweets.

A gist in R showing how to plot twitter data from ScraperWiki as a smoothScatter plot

This example shows the relationship between follower and following counts for a subset of Twitter users, revealing a dense clustering pattern near the origin with sparse outliers at higher values. The R code first retrieves JSON data from a ScraperWiki SQL endpoint, converts it into a data frame using the `rjson` package, and then renders a smoothScatter plot—a base R function that uses hexagonal binning and color density to visualize overlapping points. The plot is restricted to a 0–5000 range on both axes to focus on the majority of users while still exposing the distribution’s shape. The approach highlights typical user behavior rather than individual outliers.

Some R to knit a view on ScraperWiki

This example demonstrates how to knit an R view of ScraperWiki data into a static HTML report. The script uses the `knitr` library to render an Rhtml file, processing embedded R code and visualizations into a final web page. It relies on `render_html()` to generate the output and writes the result to an index.html file, making the data view portable and shareable. The code highlights a workflow for automating data-report generation from a ScraperWiki source.

Interactive scatterplot

This interactive scatterplot visualizes Twitter user activity by plotting tweets based on quantitative dimensions on logarithmic x and y scales, with each point colored and sized by tweet type and a related metric. The visualization includes a custom legend with lines and circles to explain the size mapping. Built with D3.js version 3.5.5, the code uses d3.svg.axis, d3.scale.log, d3.scale.ordinal, and d3.scale.linear to construct the axes and scales, with SVG rendering for all graphical elements. The dataset is loaded from a CSV file containing tweet samples, and the graph includes a title and axis labels.

Fork of Scatter Plot Using Different Data Set

This scatter plot visualizes the number of tweets per minute throughout a day, using time of day on the x-axis and tweet count on the y-axis. The SVG circles are drawn from CSV data loaded via `d3.csv` from a remote GitHub repository. The code uses `d3.scaleTime` and `d3.scaleLinear` to map the data to screen coordinates, with axes generated by `axisLeft` and `axisBottom`, and time labels formatted with `d3.timeFormat`. The visualization fills the entire browser window based on `window.innerWidth` and `window.innerHeight`.

Scatter Plot Using Different Data Set

A scatter plot displays tweets per minute across the hours of the day, using time on the x-axis and tweet count on the y-axis. The visualization loads CSV data from a GitHub repository and renders points as SVG circles. D3 v7 APIs such as `scaleTime`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` handle scaling and axes, while `selectAll` and `join` bind data to circles. Tick labels are formatted with `timeFormat` to show hour periods like “AM” and “PM.”

Fork of Fork of Scatter Plot Using Different Data Set

This scatter plot visualizes the number of tweets per minute over a day, using time of day on the x-axis and tweet count on the y-axis. The D3 v7 code loads CSV data from a GitHub-hosted file, parses the time strings into JavaScript Date objects, and renders each data point as a small circle in an SVG. It uses d3.scaleTime and d3.scaleLinear for the axes, with d3.axisLeft and d3.axisBottom adding labeled tick marks formatted as hour periods (e.g., "01 PM").

Scatter Plot Using Different Data Set

This scatter plot visualizes the relationship between time of day (GMT) and the number of tweets per minute, using data from a CSV file loaded with `d3.csv`. The code maps time to the x-axis via `scaleTime` and tweet counts to the y-axis with `scaleLinear`, rendering each data point as an SVG circle. Axes are added using `axisLeft` and `axisBottom`, with time formatted as hours using `timeFormat`. The chart fills the browser window, with a fixed radius of 2 pixels for all points.

Time of Day

This visualization plots Eric Fischer’s tweet rate per hour over eight months, collapsing all days onto a single 24-hour cycle. It uses a UTC time scale with a seven-hour offset to approximate Pacific Time, and each dot represents one minute’s average tweets per hour. The code relies on d3.v3’s `d3.time.scale.utc`, `d3.svg.axis`, and `d3.svg.symbol` to render the SVG scatterplot. Data is loaded from a CSV, with raw counts normalized by 327 days and converted to an hourly rate.
