Overview

The Stream Graph Generator creates visually engaging, stacked area charts that represent time-series data through smooth, flowing curves. It is an ideal tool for visualizing how different categories evolve and fluctuate over time, providing a clear view of trends and volume changes.

When to Use

  • •When you need to visualize the relative changes in volume for multiple categories over a specific time period.
  • •When you want to highlight trends and patterns in time-series data using a fluid, organic aesthetic.
  • •When you need to present stacked data in a way that emphasizes the overall shape and flow rather than just individual data points.

How It Works

  • •Input your time-series data as a JSON array or a simple name-value list.
  • •Customize the visual output by selecting a color scheme, baseline type, and chart dimensions.
  • •Toggle display options like grid lines and series labels to refine the presentation.
  • •Generate the chart to visualize your data with smooth, stacked flowing areas.

Use Cases

Tracking website traffic sources over several months to see which channels are growing.
Visualizing monthly sales performance across different product categories to identify seasonal trends.
Displaying shifts in market share for various competitors over a multi-year period.

Examples

1. Monthly Product Sales Trends

Marketing Analyst
Background
The analyst needs to present the growth of three different product lines over an eight-month period to the executive team.
Problem
Standard bar charts look cluttered and fail to show the 'flow' of market interest over time.
How to Use
Input the monthly sales figures for Product A, B, and C into the Time Series Data field and select the 'Vibrant' color scheme.
Example Config
chartTitle: 'Product Sales Growth', colorScheme: 'vibrant', showGrid: true
Outcome
A professional, flowing stream graph that clearly illustrates the rising and falling popularity of each product line.

2. Website Traffic Source Analysis

Content Manager
Background
The manager is reviewing traffic data from organic search, social media, and direct visits to understand audience behavior.
Problem
It is difficult to see how the proportion of traffic sources changes relative to each other using traditional line charts.
How to Use
Paste the traffic data in JSON format and set the baseline to 'Centered' to create a balanced visualization.
Example Config
baselineType: 'centered', showLabels: true, chartWidth: 900
Outcome
A symmetrical stream graph that highlights the dominant traffic sources and their fluctuations throughout the year.
