Grammer problems in writting

Could you please read this article and let me know the main Grammer problems. Thank you.

Chartjunk: Vibrations, Grids and Ducks

This article is written by Edvard Tufte. His main thesis is about unused data and ink in the information Design. He says “ The interior decoration of graphics generates a lot of ink that does not tell the viewer anything new”. Also he believe the purpose of decoration varies - to make the graphic appear more scientific and precise, to enliven to display, to give the designer an opportunity to exercise artistic skills. And his respond to this problem is that, there are better ways to portray spirits and essences than to get them all tangled up with statistical graphics.

One of the problems that he mentioned, is Unintentional Optical Art. He believe that parallel lines in chart and information design caused moire effects. Moire effect is that, when you look at a picture and the lines in that picture are to close to each other, your eyes cannot’t separate those lines from each other. In that case you fell some tremor in the picture. When we use crosshatching in a chart we have to be careful about this effect. This movement that happen in the eyes caused that we couldn't’t get those information which is in the chart. He believe that the most common form of graphical clutter, is inevitably bad art and bad data graphics. In my opinion this is a really good point that he mention. When we design a chart to give information to audience, the main propose is to give those information clear and fast. If the audience couldn’t able to get those information fast maybe they relinquish of seeing the chart.

In case of crosshatching he believe that it should be replaced with screens of varying or shades of gray. Which I believe this one is good point, because if we give our information as much as clear and flat, the audience be able to follow it. In case of technology he believe that the new technology has many advantage and disadvantage. One of the disadvantage of this technology is that the handbooks and text books of statistical graphics, along with users manuals for computer graphics programs, are filled up with vibrating graphics, and many designer use this textures in their chart design. He believe that specific areas on the graphic should be labeled with words rather than encoded with different types of hatching. Which is another good point in chart design.

In case of Grid, he believe that one of the more sedate graphical elements, the grid should usually be muted or completely suppressed so that its presence is only implicit-lest it compete with the data. Dark grid lines are chartjunk and they carry no information. So as he mentioned the solution in grid is muted line as a grid.

Other point is multiwindows or marginal plot, and of course that is part of none data inks.

Another point that he mentioned is the Duck. He says: when a graphic is taken over by decorative forms or computer debris; when the data measures and structures become Design Elements; when the overall design purveys graphical style rather than quantitative information, then the graphic maybe called a duck. He’s idea of decoration a construction is better that construct a decoration is acceptable. But his final point about the 3D charts looks more conservative. I believe there dimensional chart helps people to have a better understanding of the data. For example I myself usually understand very quickly a 3D chart rather than 2D. So despite of this point that he mentioned, the rest of his points are acceptable and useful in chart design. In the final word we can say; reducing things down to the essential elements helps the reader to read it better.
