FA: waiting for Chaals
... sharing a visual
... What we have a web gui, on the left is the specification and on the right is the chart
... first concept to talk about is navigation order
... use arrow keys to navigate the axis, there is 1 y axis
... use the right arrow key to move across , there is a green bubble visual focus

RS: what kind of information you have on the bubbles ?

FA: for sighted users what we are interested is only interactivity

RS: did not know if there is tool tip information

FA: for blind users we have more information but sighted users we are interested in interactivity only
... when you have islands and you want to hop you use the shift key
... Next is box chart, we have 2 axis, x axis is the category and y axis is the range
... depending on the statistics, there will be anomalies (outliers)
... We can cycle through the parts

Jason: is listening in

FA: use space bar to move between the parts
... next is the bar chart, x is categories and y axis the range
... when you want to move between the bars use the space bar and arrow key to move the individual parts
... stacks are important and for blind users we give totals and a tree structure

RS: one of the take away is you are grouping and then allowing to drill down

FA: able to get the stack totals and individual information is important

RS: important to provide the information of the whole stack itself

FA: could provide that in the tooltip

RS: will need authoring practices real bad

FA: lets go to the cluster bar three level
... this chart s a cluster bar with 3 x axis clustered inside

RS: how do you cycle through ?

FA: You just use the arrow keys

RS: if we have an axis that have multiple levels we need roles for nested axis

FA: for blind users this will be represented as a tree and you will get all the information

RS: axis can have levels with multiple levels

FA: the bars are much more important when they have levels

RS: we need to make sure that any nesting and group should have roles and can drill down

FA: With clustering it is quite normal to have multiple levels
... jump to move to relationship in a tree
... we provide relationship in a tree

RS: are you using flowto to navigate ?

FA: not yet
... the nodes coming out are visually highlighted with different colors
... use arrow keys to move to the nodes
... We give a forward path and highlight the flow from path

RS: So how do you show the differnce in color some other way ?

FA: primarily it is only by color, could add border thickness, by default we do not
... option to highlight direction relationship
... In this graph is 3graph, with a bar char rotated by 90 dgerees and 2 pie charts
... for multiple graphs to move between the graph is important
... should be able to move between views and keep the point of regard
... Next is a Chord chart
... has 2 conceptually different sections with ribbons that connect them
... we have severities
... Next is another chord chart with countries in the outer circle and ribbons represent surplus that connect them
... on the out side use arrow keys to move around the circle, for the ribbons use space bar to get within
... ribbons represent relationships
... Chord charts are complex with multiple parents

Chaals: different way to represents different graphs
... this representation makes it easy to navigate

<Zakim> LJWatson, you wanted to say it essentially comes down to data, relationships and context.

AB: When connector is not highlighted how do you which direction it is following ?

Chaals: the idea that there is dominant parent is pointless

CP: Thank you

FA: main point across is there is lot of relations ships and data to navigate

Chaals: what is a sensible way to do navigation that is structured
... what is the minimum information needed to describe the navigations

AB: different way to navigate, navigate by relations, need to define multilevel navigation

FA: having a common repository is a good way to start

Chaals: use the community repository , will send an email

RS: like to do reach out to oracle to show their work

Chaals: put together a suggestion to meet in Europe, SVG group and others

Amy: i am from oracle group

RS: Amy do you charts to show ?

Amy: yes we can show some

FA: using tab key is difficult to navigate complex charts

RS: Fred you have an idea to navigate

Chaals: you have triangles inside triagles
... pick a triangle, navigate logically
