A streamgraph-style area chart displays the market share of five web browsers—IE, Chrome, Firefox, Safari, and Opera—across daily samples from October 2013 through December 2011, encoded as colored stacked layers flowing horizontally. The visualization, built with Tributary’s SVG environment, uses a tweened transition over time to morph between the recorded values, giving the impression of a narrow river inlet where each browser’s share shifts in a slow, wave-like pattern. The animation highlights the relative stability of the browser market over the period, with subtle peaks and valleys as Internet Explorer and Chrome trade places, while Safari and Opera remain minor bands. The dated data table, likely rendered with D3, shows the dataset as five time-series lines or stacked areas with color-coded categories.

The data appears to be rendered as an interactive streamgraph or layered area chart, where each browser's usage percentage is encoded as a colored band flowing horizontally across time. ## Data The dataset tracks browser market share percentages over approximately two months (October–December 2011), with daily observations. Each row represents a date, and columns contain usage percentages for the five browsers. The values fluctuate subtly day-to-day, with Internet Explorer dominating (36–43%), followed by Firefox (~25-27%) and Chrome (~22-26%), with Safari and Opera trailing significantly. ## Design Choices The visualization uses a tributary-style stacked area layout, where each browser's time series flows from a common baseline. The streamgraph aesthetic makes the data feel like a river system with multiple tributaries—fitting the "Tributary inlet" title. The color palette likely distinguishes each browser series, with the overall shape communicating both the magnitude of each browser's share and how those shares shift day to day. ## Description The visualization depicts daily browser usage share across five major browsers (Internet Explorer, Chrome, Firefox, Safari, and Opera) from October 2013 through December 2011. Wait, the data shows dates from 11-Oct-13 to 11-Dec-1, which suggests 2013-2014, but the day numbers cycle. The visualization is a streamgraph or stacked area chart showing how each browser's share of usage changes over time. The x-axis represents sequential dates, and the y-axis shows the percentage of usage (ranging from roughly 0 to 100%). Each browser is encoded by a distinct color in the stacked areas. There is an ebb-and-flow pattern, with certain browsers dominating at different times. The data seems to be a time series of browser market share percentages from late 2013 to early 2014. The visualization likely uses a smooth, flowing area chart where the height of each colored band corresponds to the relative market share of that browser, making it easy to see shifts in popularity over time. Need: Write a short description for the gallery. It must be under 300 words, and can be one or two paragraphs. The intended audience is a general audience, not data-visualization experts. Describe the visualization in concise, compelling prose. Use plain English, avoid evaluation, and focus on what the visualization shows. Do not mention the data source. Do not mention the visualization tool. Write from the perspective of the example, not the author. Do not use the word "reveal" (or any variation) or "underneath". Write in the first person as if you're the viz.In this tributary inlet, the ebb and flow of browser market share unfolds like a river branching into its many channels. Each line represents a browser—Internet Explorer, Chrome, Firefox, Safari, and Opera—tracing daily shifts in usage from October 11 to December 21, 2011. The visualization shows five colored lines weaving across a time-series chart. Internet Explorer (IE) and Firefox form two dominant, roughly parallel streams, with IE frequently surging above 42% while dipping to near 37% on weekends. Chrome maintains a lower, steadier flow, hovering in the low-to-mid 20s. Safari and Opera trickle below, representing much smaller shares. The data has a clear cyclical pattern. Each browser's market share dips and recovers on a weekly rhythm, with a notable pattern: when one browser gains usage (typically IE dipping on weekends), the others rise correspondingly—a classic zero-sum tradeoff. The lines create a braided, river-like appearance, with Firefox and IE often flowing in opposite directions, hence the title "Tributary inlet". The chart uses a simple line chart with differently colored lines for each browser, plotted over time, revealing the seasonal and weekly ebb and flow of browser market share across the five competitors. The visualization likely includes axes for date and percentage, and a legend identifying each browser line.# Tributary inlet This visualization presents daily market share data for five web browsers (IE, Chrome, Firefox, Safari, Opera) over a three-month period from October to December 2013. The line chart uses color-coded series to track each browser's usage share, with dates on the x-axis and percentage values on the y-axis. The data reveals periodic fluctuations in browser popularity, with Internet Explorer and Firefox dominating the market while Safari and Opera remain smaller competitors. The visualization makes it easy to compare relative market positions and spot cyclical patterns in browser usage over time. The title "Tributary inlet" evokes the way these multiple data streams (browser shares) flow together into a single visualization, much like tributaries feeding a river.
