## Abstract

A method and system for Java Gantt/bar chart rendering includes an extractor to receive project data, a table generator to generate a project table suitable for representing the project data, and a dynamic page component to generate a Gantt chart image utilizing the project table. The system further includes a cell rendering component to render at least one cell of the project table by identifying a suitable graphical image and by applying the graphical image to the cell.

### Claim 7 (depends on 6)

The system of claim 6, wherein rendering the at least one cell of the project database table includes applying the background color to the at least one cell if the project data corresponding to the at least one cell is one of a full time unit and an empty time unit.

### Claim 8 (depends on 1)

The system of claim 1, wherein the project data includes a project name, the start date of the project, and project duration.

### Claim 9 (depends on 1)

The system of claim 1, wherein the processor further generates an event related to the at least one cell, the event being utilized to display additional information responsive to identifying an action directed at the at least one cell.

### Claim 10 (depends on 9)

The system of claim 9, wherein the action directed at the at least one cell is a click.

### Claim 11 (depends on 1)

The system of claim 1, wherein the chart image is a dynamic web page.

### Claim 12 (depends on 1)

The system of claim 1, wherein the processor sends the chart image to the client device for display utilizing a web portal.

### Claim 13

A computer-implemented method to automatically create a chart for display on a display device, the method including:
receiving project data associated with a data model, the associated data model suitable for representing project data extracted from a project database associated with a client device;
generating a project database table representing the extracted project data based on the associated data model;
identifying a table view model suitable for representing the extracted project data, the table view model containing a location in a graphics repository of graphical images for representing the extracted project data;
generating a table view of the extracted project data in accordance with the identified table view model;
generating a chaff image utilizing the project database table in accordance with the generated table view, the chart image being one of a Gantt chaff and a bar chart; and
displaying the chart image on a display device.

### Claim 14 (depends on 13)

The method of claim 13, wherein the generating of the chart image utilizing the project database table in accordance with the generated table view includes rendering a cell of the project database table, wherein the cell represents a portion of the chart image corresponding to a portion of the project data represented in the project database table.

### Claim 15 (depends on 14)

The method of claim 14, wherein the rendering of the cell includes identifying a graphical image in the graphics repository to depict the corresponding portion of the project data represented in the project database table from based on the location contained in the identified table view model and applying the graphical image to the cell.

### Claim 16 (depends on 15)
