Fertilizer Imports/Exports Data - USA

Data Set can be found here.

Planned Tools

• Python and R to pre process the data
• D3 for developing prototypes
• D3 for final visualizations

Planned Techniques

Multi Series Line Chart

• Time series of total value of each commodity (fertilizer)
• It can be either Volume (in tons) or ammount (in dollars)
• Import/Exports plots will be shown side by side
• This plot gives an overview of changes in the volume/dollar value of each commodity over the time

Choropleth

• Country wise annual U.S. imports and exports
• It can be either volume (in tons) or ammount (in dollars)
• Tone of color is used to encode the volume
• Either Import or Exports data wil be shown by toggling a button
• A slider will be provided to change the time (Year)
• Top three commodities by country information is shown on hover
• This plot gives an overview of total import/exports volume/dollar value by country

Circle Packing

• Country wise annual U.S. imports and exports
• It can be either volume (in tons) or ammount in dollars
• Size fo bubble is used to encode the volume
• Either Import or Exports data wil be shown by toggling a button
• A slider will be provided to change time (year)
• This plot provides information about the contribution of each country, commodity to total import/exports volume/dollar value

Scatter-Plot Matrix and Heat Map

• Upper Triangle- Scatter plot matrix of annual U.S. imports and exports by commodity (fertilizer)
• Lower Triangle - Exact correlations between the commodities
• Color is used to code the correlations
• It can be either Volume (in tons) or ammount in dollars
• Either Import or Exports data wil be shown by toggling a button
• A slider will be provided to change the time (Year)
• This plot provides insights into co-occurences of commodities

Planned Interaction

• A button indicating either volume (in tons) or ammount (in dollars) at top level, which is applied to all the visualizations (Linked Interaction)
• Details on demand (on hover) for multi series line chart
• Linked Import/Exports button for Choropleth and Circle Packing
• Linked slider for changing the time (year) for Choropleth and Circle Packing
• Details on demand (top 3 commodities for highlighted country) on hover for Choropleth
• Highlighting the country/bubble on hover (Linked Interaction) for Choropleth and Circle Packing
• Zooming functionality for Scatter-Plot Matrix
• Import/Exports button and time slider for Scatter-Plot Matrix

Planned Interface

Layout of the proposed visualzation is shown below.
